My 03 hit 140,000 a few days ago and started misfiring today when I took it out, was pretty confident I could learn how to change spark plugs but I'm glad I watched this! Don't want to make it a $1000+ problem so I'll probably take it in to get done. Love your channel it's incredibly helpful! I wouldn't be an expert at 350z door panels if it wasn't for you!🤣

@@nachopen nice just got back from a ride in my 2006 rev up convertible, I live in California in my mind the convertible had that fun factor that i could abuse in California. Glad you got your 350z !!!!!
I’ve watched a few of your videos and one thing I think would help people is if you told us what size sockets you use when completing different jobs. I noticed you put a lot of detail into these videos except for that.
I just recently picked up a Z and I was told it developed a misfire and it’s for sure the spark plugs. The engine is bone stock it just has an exhaust and a performance , flame , and economy tune. Would any of that effect what type or kind of spark plugs I should get? And would I have to take it to that specific tuner or could I just take it to a local shop since my motor is stock?
You can take it to a local shop that is familiar with Nissan engines. I list some part numbers in the description. Also look into changing out the camshaft and crankshaft position sensors, if original they cause issues at this age of the vehicle.
Great video ! ! What about the other side ? ? I don't mean to sound like a fink, but there's another side to change out and there's not a lot of room on that side either. Is there anything to look out for as a pre-caution or any tips for the other side ? ?
Hi Anthony, I have a G35 and about to change my sparks for the first time. In the video, you mentioned to hand tight the spark plugs and then torque wrench it according to manufacture specs. Where can I find this? And another video showed that I would need to remove the intake manifold gasket, would you say this is needed?
Jamilynn Nguyen I didn't pull out the manifold. The torque setting would be in a service manual. You'll want a very accurate torque wrench because you can strip the threads. Or you can just make them snug by feel. Just be gentle with them because the cylinder head is aluminum which is a soft metal.
I have my own way of doing this job, to me which is way easier. Unplug the harness and walk it out, you’ll have all the space you need and it doesn’t take much time
So I drift my 350Z, during the process of swapping these out my two rear coil packs and the ports were super oily, like when you pulled the pack out you could hear the oil gloop inside, I was just like “oh boy this is fun” I cleaned everything up real good and dropped in all 6 plugs and replaced the two rear packs as they were bad, I’ll need some valve cover gaskets at some point soon though 100%, or it blows up and I slap another VQ in🤷♂️
I currently use and have only used Mobil 1 Full Syn 5w-30 and that was what the previous owner ran always as well (I’m lucky I bought it from a friend who took really good care of it) but yea 100% valve cover gaskets are getting done!
what do you prefer a turbocharged g35 or supercharged...i know the supercharge is more reliable...and less horsepower.. turbo is more power ...but you do get turbo lagg sometimes depends what setup you have... what do you think?
I would go super charged for the simpler and more cost effective set up. If you can put 350 to 400 horsepower to the ground, that is a fast street car. But I would spend money first on suspension and brake to help use the power you already have and if you do the big upgrade, the chassis can keep up with the motor.
what is the best brakes i can get for my g35 and suspension and how much? this car is my daily driver...thinking bout keeping it for 4 years or less. by the way i just got my clutch fixed...the problem was the clutch will get stuck in the bottom....i had to get my left foot and put it under my clutch to pull it out again...i had a little trouble changing gear...they told me that supposedly there was something loose in the clutch. what do you think? ok well supercharger it is... ive never seen a g35 with a supercharger before. will you supercharge your 350z?
Hmmmm probably something in the hydraulics of the clutch have gone. The master, slave or both need to be replaced. Change out the flex line to a stainless braided version with a heat shield as well. I doubt I'll supercharge mine, too much money right now and I have another vehicle to work on and I want a house. I'm just doing the plenum spacer and I'll be good for power right now with my full exhaust. You should look into changing the diff bushings and transmission mount and put more power to the ground.
Is your car misfiring? You can get a spark plug testing tool or swap the coil to the other side of the engine with a good one and see if the misfire code switches to the other bank.
Wich spark plugs would you recomend for a VQ35DE??? Would you recomend the iridiums? I want to make more power 😅 I was thinking on getting the oem ones but idk 😥
I run Iridiums and have no issues. Spark plugs won't help make "more" power, just restore it because the old ones might not be operating as efficiently.
The only thing I'll quote is: no matter what, always check the gap. They say they're pregapped from the factory yet in the past none of the gaps were precise. So just a rule of thumb
After i finished changing the spark plugs, i turned the car on and it had a rough idle. Kind of like it was choking anf the service engine soon came on. I asked a mechanic friend and he told me to just drive it a bit to break the spark plugs in because the old ones were super used up. It would have a rough take off when accelerating from a stop. Do you have any idea what it could be? I really need to know because i drive this to work, any tips would be appreciated.
@@AnthonyJ350 im pretty sure i pluugged everything in. It drives smooth if im going a constant speeding but if i decide to push it a bit it picks up speed roughly and it takes off roughly as well. Its like its letting out gas bubbles through the exhaust im not sure how to explain ive never seen this happen before. Another thing is that the service engine soon was constantly on and when i drove on the highway it began flashing
@@martindeanda650 Did you use double platinum or better plugs? Also you should inspect the gap. They're pregapped but could get pushed in during shipping.
@@AnthonyJ350 i got the double iridium ones and i honestly forgot to check the gaps. They were pregapped but i should've checked them again. I'll see if i check them today
Why would you ever go out and source vaccuum hose to thread a spark plug in, when you just stick them back in the plug socket and thread them in? Stacey just likes to play with limp hose. Good vid man!
Did you see the cylinder head design? You can't thread it in by hand because your fingers won't reach, so you end up dropping them in so you might affect the ground electrode. Watch that section again. Thanks for watching!
hahaha.....just the tip! too funny! Hey you didnt really dive into the last 2 spark plugs on the passenger side closest to the firewall. For someone like me who has little experience mechanically working under the hood, just how hard is it to get to these last 2 plugs? Am i going to have to remove & disconnect alot of wires and bolts? Thanks again for ALL your vids! You have really helped me and taught me alot about my 350. I love my car and want to take care of it and am thankful for another Z enthusiast like yourself.
Hey anthony...i turned on the vehicle and chk engine, tcs and slip lights came on...i am going to borrow a scanner but do you have any idea what this could be...also it does not rev over 2,000rpm
Why iridium ix and not laser iridium? There's quite a huge difference in their milage. I guess your revup is easy but HR motors can be hard for some people so they may put long life plugs 💪😐
NGK states these are designed for the performance enthusiast and the electrode on the Laser is smaller (I'm guessing for longer life). Given I only drive the car 8 months out of the year these should do me fine for the application.
hey Anthony, i wanted to ask you, if i am about to change my spark plugs in my 06' 350z should i also be changing my coil packs as well?? I havent changed the spark plugs in more than 5 yrs. (i know, long overdue) and the coil pks have never been changed. I trust your opinion and adhere to your advice in all your 350z videos. Thanks again!
Mike Bonez If they're firing fine just change the plugs. Changing the coil packs can be very costly. Just inspect them and try to clean the area that makes contact with the spark plug.
Hello Bro,,, Wats the best Spark plugs for 350z HR 2008 other than NGK? What do u suggest plz help. My car is in perfect condition but i checked Spark they are burned from top and also consuming too much Petrol
No .. Wanted to search and Ask owners of 350z here In YT first. I will go 2moro... but buddy if i install new from nissan geniune parts..will fuel consumption decrease ? Even a tiny bit will be good if does. Also does it make the car perform better more hrspower??
@@isoooalrock You're definitely restoring power and efficiency with fresh plugs. Driving habits and tire pressure also have a big affect on fuel consumption.
Those are not OEM.. Use the double platinum.. most autoparts don't carry them on the shelf but almost any Auto Parts can special order them for you and usually they will try to push these as OEM instead.. the logic is that iridium is actually a better material however the OEM double Platinum have more surface area and the electrode is beefier so in actuality the OEM is way better.. the OEM can get a little bit pricey though.. I have owned my vq35de since new and using the OEM yields the best results..
psychobilly The longer service life doesn't interest me because I wouldn't use the plugs for over 100,000 KM. But what's the price difference? Because if it's like double it doesn't make any sense since the Iridium is pretty durable.
AnthonyJ350 well well although they are more expensive it's not as bad as it used to be where as iridium for example would set you back $7.99 a piece the double Platinum will run you about $11.99 a piece.. for a enthusiast I would recommend they go with the OEM it is a nominal investment to compliment any upgrades or modification they have made whereas to an average Joe they might not notice or care about the difference in performance so much.. the double Platinum will have a very consistent reliable life span whereas the iridium you will have a noticeable decline in performance after about 75% of its life span.. furthermore my friend for example has a fully built twin turbo vq35de and the shop that Built his engine recommended even he use the OEM plugs although depending on the application you can go a couple of degrees cooler on the spark plugs you will also find reference to this in the 350Z owner's manual..
Hey man I know I’m late but tonight I realized trying to start my de engaging the clutch to ignition switch it would not crank over but it was knocking really loud could it be spark plugs?
I’m sorry, the car had the codes p0011 and p0021 so it won’t turn over when I try to crank and when it does it’s in sort of a limp mode sounds like a train on the tracks. Won’t not drive, I have not changed the spark plugs nor the vvt solenoids but the cam sensors and crankshaft.
@@AnthonyJ350 my VQ35HR is not modified, but I replaced spark plugs with brand new denso OEM ones and its electrodes were all gone (melted) after driving 34,000 km.. And number 1 and number 2's O-rings where spark plugs are were leaking... I was wondering if it's better I use 1 colder spark plugs or not...
Great video. I own one of the first group of Z's that showed up in 02 and still love it very much, I need to change the plugs and need help on indexing them as you mentioned in the video, how did you do the indexing? Did you mark the plug then use shims? Your help no guidance will be much appreciated.
Thank you! It's had a few changes since this video. I noticed little bit better throttle response, the plugs I took out weren't bad. I think the manual states their good for up to 100,000KM but for how cheap they are I change them around 60-70,000KM. After 2 years I'll random pull out a couple at the very least to see how they look and if anything looks amiss.
AnthonyJ350 yes , i am in the same situation 64000 klm = 40000 miles in USA approximately, my Z runs smooth actually but maybe could be better if I change the sparks now , I will buy iridium again , I think is the best option , thank you 😊

@@AnthonyJ350 Yeah through the seal and the gasket. There was some oil in cylinder 2, none in 4 and a lot in 6. I haven't checked the passenger side yet.
+AnthonyJ350 well it says here on paper from the dealership that the cause from my clutch was the master clyinderloosing pressure. the correction they did was that they replaced the clutch master cylinder and the bleeding system something like that i dont know what that is. also they diagnosed the transmission and drive train
Ivan Padilla yes you should always properly torque spark plugs because like he said you don't want exhaust gases leaking, spark plugs coming loss, loss of compression, or the spark plug to be over tightened and break off or be at the improper height.
i have rear seats installed in my 350z . from a g35. not really much room or safe to put anyone in.... but makes a great "accessable trunk" area to put things in.
xXYannuschXx Ya if it works for you I see no issues. I just find with some magnets for the installation portion a fastener or plug may just spin on the magnet.
how i can change the coil extension when is broken on the internal ? I have the extension coil but im not sure how i can do it ...and i actually need to be sure if it comes out under pressure or it does have to be with some kind of tool
I changed my spark on my Hr, at 1st gear when it idles I roll the car (give it gas) as I accelerate into 2nd gear I feel as if the car kind of chokes/hesitates. Could it be a loose spark?
Quick question anyone feel free to answer. I just got a 350 2005 and whenever I drive it hard it smells like burning oil. I don’t know if it’s coming out of the exhaust or if it’s leaking somewhere. It has Berk test pipes and nismo full exhaust
It's probably because of the test pipes. It should only blow some black smoke under hard acceleration. If it's blue it's burning excessive oil. When was the last time the PCV valve was changed?
Well this is as close of a video I have what it would take to put rear seats in, minus cutting the roof. You do know you'll have to pretty much redo the entire interior in the back to make it look finished. You are better off selling your 350Z and buying a G35 coupe, it'll be cheaper. ua-cam.com/video/oLa5ZAEZrN4/v-deo.html

I just attempted this yesterday and now my car shakes and the service engine soon light is now on. Gap is set to oem and everything has been put back together accordingly. Anyone had this problem?
Scan it and see what area is being affected. I'm willing to be the air intake tube is folded on one of the connectors up underneath letting air in so the MAF can't measure air properly.
I got the same problem now, No error code, no engine light, replaced the whole spark plug, * At the first time, I just cleaned out the coil bay, and it worked but now It doesn't.
What Spark plug specifically? Mine started backfiring really badly lately and I wanna make sure I buy the right plug... seen people buying both NGK Lfr6a11 and lfr5a11 and I’m curious as to what you are running?
I just use the one NGK recommends that is only Iridium on the electrode while the ground is the regular material. The ground electrode won't last as long but dissipates heat better than an Iridium ground electrode. My engine is also relatively stock.
"Don't trust no one when you bought the car used" well said man well said!
Ivan Padilla Hahaha well you can't. There's a reason they're selling it right?

You should look into changing the diff bushings and transmission mount and put more power to the ground.
Optional brakes would be Brembo. It's popular to get the conversion kit for the cars and put the Akebono brakes off the 370Z on them.
Do i have to jack the car up to take the load off the strut bar when removing? Or just can i remove it with the car level?
You can just remove it. Make sure to release each bolt in stages gradually and retorque to spec after.

Mileage intervals typically. I would just pull out one to check their condition.
I use the Ngk laser platinum plug the only part I hate it’s 82 bucks for 6 plugs but it’s a great plug
Gotta pay for quality.
What size spark plug socket?
My 14 mm (9/16 in) socket is just spins inside chamber even though it fits new spark plug.
Buy a spark plug socket set so you're prepared for any situation.
Hello anthony...question, can a loose spark plug cause the car to go on limp mode sometimes?
William Westerband Jr. You would probably hear a knocking as well. Does it sound like you have an exhaust leak?
AnthonyJ350 i do hear a ticking when in idle
William Westerband Jr. Pull the coil out and see if there's black soot build up. That would indicate a loose spark plug.
AnthonyJ350 thank you...will do...hopefully that will solve problem...it just started 2 days ago all of a sudden...great channel.
Hey anthony...i turned on the vehicle and chk engine, tcs and slip lights came on...i am going to borrow a scanner but do you have any idea what this could be...also it does not rev over 2,000rpm
So a exhaust leak would cause poor performance as you car not running as fast as you want? Or is that just a problem with camshaft sensors?
Can you hear a ticking sound near the exhaust?
AnthonyJ350 i bear a tick in mine!
What’s the size for the spark plug socket
I would just buy a socket set that has 3/8 and 5/8
Why iridium ix and not laser iridium? There's quite a huge difference in their milage. I guess your revup is easy but HR motors can be hard for some people so they may put long life plugs 💪😐
NGK states these are designed for the performance enthusiast and the electrode on the Laser is smaller (I'm guessing for longer life). Given I only drive the car 8 months out of the year these should do me fine for the application.
How about showing how to do the passenger side? It’s a lot tougher
I thought the driver's side is harder since there's more things in the way. The passenger side wasn't bad at all.
hey Anthony, i wanted to ask you, if i am about to change my spark plugs in my 06' 350z should i also be changing my coil packs as well?? I havent changed the spark plugs in more than 5 yrs. (i know, long overdue) and the coil pks have never been changed. I trust your opinion and adhere to your advice in all your 350z videos. Thanks again!
Mike Bonez If they're firing fine just change the plugs. Changing the coil packs can be very costly. Just inspect them and try to clean the area that makes contact with the spark plug.
AnthonyJ350 , awesome! Thanks again buddy!

Hello Bro,,, Wats the best Spark plugs for 350z HR 2008 other than NGK? What do u suggest plz help. My car is in perfect condition but i checked Spark they are burned from top and also consuming too much Petrol
Why not put NGK Iridiums in?
They fit in VQ ...I dont they are for HR 2007-2008 model. I searched online for HR engine not available
@@isoooalrock HR is a version of the VQ. Did you try calling your local auto parts store?
No .. Wanted to search and Ask owners of 350z here In YT first. I will go 2moro... but buddy if i install new from nissan geniune parts..will fuel consumption decrease ? Even a tiny bit will be good if does. Also does it make the car perform better more hrspower??
@@isoooalrock You're definitely restoring power and efficiency with fresh plugs. Driving habits and tire pressure also have a big affect on fuel consumption.
Those are not OEM.. Use the double platinum.. most autoparts don't carry them on the shelf but almost any Auto Parts can special order them for you and usually they will try to push these as OEM instead.. the logic is that iridium is actually a better material however the OEM double Platinum have more surface area and the electrode is beefier so in actuality the OEM is way better.. the OEM can get a little bit pricey though.. I have owned my vq35de since new and using the OEM yields the best results..
Better throttle response?
What are the improvements? Can you see it on a dyno or feel it at least?
Yes I think the main difference is throttle response, and the OEM plugs have a longer service life then those other Autoparts variants.
psychobilly The longer service life doesn't interest me because I wouldn't use the plugs for over 100,000 KM. But what's the price difference? Because if it's like double it doesn't make any sense since the Iridium is pretty durable.
AnthonyJ350 well well although they are more expensive it's not as bad as it used to be where as iridium for example would set you back $7.99 a piece the double Platinum will run you about $11.99 a piece.. for a enthusiast I would recommend they go with the OEM it is a nominal investment to compliment any upgrades or modification they have made whereas to an average Joe they might not notice or care about the difference in performance so much.. the double Platinum will have a very consistent reliable life span whereas the iridium you will have a noticeable decline in performance after about 75% of its life span.. furthermore my friend for example has a fully built twin turbo vq35de and the shop that Built his engine recommended even he use the OEM plugs although depending on the application you can go a couple of degrees cooler on the spark plugs you will also find reference to this in the 350Z owner's manual..
Hey man I know I’m late but tonight I realized trying to start my de engaging the clutch to ignition switch it would not crank over but it was knocking really loud could it be spark plugs?
Knocking while idling and driving? What's the oil level? What fuel grade are you putting in?
AnthonyJ350 oil looked kind of corroded 10w-30 for hotter climates and fuel grade has always been 91
I’m sorry, the car had the codes p0011 and p0021 so it won’t turn over when I try to crank and when it does it’s in sort of a limp mode sounds like a train on the tracks. Won’t not drive, I have not changed the spark plugs nor the vvt solenoids but the cam sensors and crankshaft.
@@dylandodson5215 Try 5W40 Castrol synthetic and take out the spark plugs and inspect them
Is it safe to use denso req. 8 spark plugs on vq35hr instead of denso req. 7 one?
Not sure, is the heat range same as stock? Are you modified?
@@AnthonyJ350 my VQ35HR is not modified, but I replaced spark plugs with brand new denso OEM ones and its electrodes were all gone (melted) after driving 34,000 km.. And number 1 and number 2's O-rings where spark plugs are were leaking... I was wondering if it's better I use 1 colder spark plugs or not...
@@Qkfltpdls777 If the spark plugs were leaking oil you might need new seal for the valve cover. I would run the factory heat range since it's stock.

Great video. I own one of the first group of Z's that showed up in 02 and still love it very much, I need to change the plugs and need help on indexing them as you mentioned in the video, how did you do the indexing? Did you mark the plug then use shims? Your help no guidance will be much appreciated.
I just try to install them all in the same orientation with the tip facing up or down on all of them.
Great video
osman lopez Thank you!
Torque specs for spark plugs?
15lbs
I just snug them up.
Hi, Did you feel the difference between before and after changing the sparks? And how often do we have to do this in our Z? Nice Z by the way 👍🏻
Thank you! It's had a few changes since this video. I noticed little bit better throttle response, the plugs I took out weren't bad. I think the manual states their good for up to 100,000KM but for how cheap they are I change them around 60-70,000KM. After 2 years I'll random pull out a couple at the very least to see how they look and if anything looks amiss.
AnthonyJ350 yes , i am in the same situation 64000 klm = 40000 miles in USA approximately, my Z runs smooth actually but maybe could be better if I change the sparks now , I will buy iridium again , I think is the best option , thank you 😊
@@andreslatorre1466 Also consider upgrading the grounds under the hood to help out all the electronics work better ua-cam.com/video/mkWCqSfr6ig/v-deo.html
AnthonyJ350 thank you , also last question , sorry to bother u again 😂, since I bought my Z , I never been change spark plug wire , did you do this? Which brand? Oem? ✌🏻
@@andreslatorre1466 It's coil on plug so there's no spark plug wire to change out. Just swap out an ignition coil if it ever goes bad.
Not sure if you have went over this before, but where did you get those covers for the battery and master cylinder?
They're factory
Hi, can you please tell me what spark plugs are recommended for a infiniti fx 35 2004? Thanks in advance
Did you check the owner's manual?
How often should spark plugs be changed ?
It'll tell you in your owner's manual.
How often do u do yours ?
My truck 80,0000km. My car I'll probably change after 4 years depending on how it looks. I don't drive it a ton.
after changing coil packs and spark plugs , my car wont crank or start at all , not even a click . it'll start while having an obd reader connected to it . idk if its a ground issue or what , please help
I would check the voltage at the battery, all the fuses and factory relays. Also check the factory grounds.
8:00 I HATE that Snap On light. It's great when it works....but that's the first year or two when you first bought it 😑
Your dealer dealer wouldn't warranty it? It is an electronic device and it's at their discretion. I would look into Milwalkee for products like this.
Hopefully this works... my Z is misfiring and I'm running out of ideas on what it could be.
Could be an ignition coil
@@AnthonyJ350 Turns out it was the valve covers. F'in RIP.
@@BigBoyz33 Did they leak oil through the seal?
@@AnthonyJ350 Yeah through the seal and the gasket. There was some oil in cylinder 2, none in 4 and a lot in 6. I haven't checked the passenger side yet.
do the g35 and 350z have xemon headlights or hid headlights?
Xenon is typically the gas used inside an H.I.D. lighting system. So yes. Depends on the year.
+AnthonyJ350 ok well i have a 06 g35
If it's like a 350Z it would have H.I.D.'s already.
+AnthonyJ350 yeah well isnt a g35 a 350z only with a backseat?
+AnthonyJ350 well it says here on paper from the dealership that the cause from my clutch was the master clyinderloosing pressure. the correction they did was that they replaced the clutch master cylinder and the bleeding system something like that i dont know what that is. also they diagnosed the transmission and drive train
Do you really have to torque the spark plugs ?
Ivan Padilla yes you should always properly torque spark plugs because like he said you don't want exhaust gases leaking, spark plugs coming loss, loss of compression, or the spark plug to be over tightened and break off or be at the improper height.
could u put rear seats on a 350z?
Not the way this car is shaped and all the bracing in the back. If you want rear sears you have to go G35 or G37.
i have rear seats installed in my 350z . from a g35. not really much room or safe to put anyone in.... but makes a great "accessable trunk" area to put things in.
blake williams Whoa do you have a video of this? I’ve never heard of a (350z with rear seats
Just got me a 2004 350Z thing idles up and down and. eventually dies any idea what im looking at bro

AnthonyJ350 Not yet have work but I will
Couldn't you also use a magnetic spark plug nut?
To pull them out or to install?
Both, I used one on my car. You can get them quite cheap on Ebay and they work pretty well.
xXYannuschXx Ya if it works for you I see no issues. I just find with some magnets for the installation portion a fastener or plug may just spin on the magnet.
Was able to do right side just removing air system and one bracket in middle and on front right
Good job!
I put these in my 350z now it runs very rough. All spark plugs had the same gapping so im confused as to what went wrong.
If you noticed a variation in gap this video might help ua-cam.com/video/3HtAJcizVnE/v-deo.html
What type of plug and what was the heat range? Is the car stock? Is the intake tube installed correctly?
Just got some original ones at Nissan,just bought a 03 with 125.xxx miles stock original and I think the previous owner never had changed.
Were they hard to get out at all?
Couldn’t get coil pack in back left and found the rubber stayed on the plug from the socket 😡
Put a little dielectric grease when you reinstall
how i can change the coil extension when is broken on the internal ? I have the extension coil but im not sure how i can do it ...and i actually need to be sure if it comes out under pressure or it does have to be with some kind of tool
I changed my spark on my Hr, at 1st gear when it idles I roll the car (give it gas) as I accelerate into 2nd gear I feel as if the car kind of chokes/hesitates. Could it be a loose spark?
It didn't do it before? Is it making a ticking sound when it idles?
my 350z is miss firing, can it be a spark plug issue?
Did it throw a code?
Mine is missfiring code is PO300
Did you buy the spark plugs from amazon.ca?
Nope my local parts store.

Check out rockauto.com and search their NGK Iridium plugs.
At 11:37 the black plastic that you touch what does it call? I'll appreciate it
NEW Songs TV It's called "loom". The factory wiring harness is inside. It manages the wire and helps protect it.
can i use hks m40 spark plugs on bolts on untuned 350z de ?
Never tried them, NGK is my preferred choice for all of our vehicles.
Quick question anyone feel free to answer. I just got a 350 2005 and whenever I drive it hard it smells like burning oil. I don’t know if it’s coming out of the exhaust or if it’s leaking somewhere. It has Berk test pipes and nismo full exhaust
It's probably because of the test pipes. It should only blow some black smoke under hard acceleration. If it's blue it's burning excessive oil. When was the last time the PCV valve was changed?
I thought the plugs on my L67 Regal were complicated, but this looks just as difficult if not worse!
It's not horrible. I prefer this over a FWD V6 but it's still a decent amount to consider so you don't hurt the car.
AnthonyJ350
Yeah the trans verse mounted engines suck lol
and if yes could u do a tutorial
Well this is as close of a video I have what it would take to put rear seats in, minus cutting the roof. You do know you'll have to pretty much redo the entire interior in the back to make it look finished. You are better off selling your 350Z and buying a G35 coupe, it'll be cheaper.

luunyjvtuun - Your car will get erectile disfunction.
Then you will have to do the painful pedal, throttle, and idle relearning procedure...
I just attempted this yesterday and now my car shakes and the service engine soon light is now on. Gap is set to oem and everything has been put back together accordingly. Anyone had this problem?
Scan it and see what area is being affected. I'm willing to be the air intake tube is folded on one of the connectors up underneath letting air in so the MAF can't measure air properly.
Do I absolutely need to use dielectric grease? Or just highly recommended? I assume I can pick this stuff up from my local Walmart or autozone?
Av8tor highly recommended. You can get it most automotive places
I got the same problem now, No error code, no engine light, replaced the whole spark plug, * At the first time, I just cleaned out the coil bay, and it worked but now It doesn't.
What's not working?
What Spark plug specifically? Mine started backfiring really badly lately and I wanna make sure I buy the right plug... seen people buying both NGK Lfr6a11 and lfr5a11 and I’m curious as to what you are running?
I just use the one NGK recommends that is only Iridium on the electrode while the ground is the regular material. The ground electrode won't last as long but dissipates heat better than an Iridium ground electrode.
My engine is also relatively stock.
why do you only change 3?
Aaron Huynh I changed all 6, just showing you the harder side to work on for the video
Why can’t I find a UA-cam video showing the exact number and places of the spark plugs smh
You should probably bring your car to a mechanic.
1,3,5 is on the left and 2,4,6 is on the right near the air intake.... I’m good buddy. Thanks though for helping.
