The Power ratchet must make this process much faster. I need one of those. I’ve recently learned “ HOW TO” change spark plugs, only because our local shop is about 2 months out on any repairs and or regular car maintenance. This Video is a great help to many people like me, so THANK YOU SO MUCH! I appreciate you taking the time to both video and explain this process, while not ( IMO ) wasting time. The Lexus LS430 is a great car and back in the day was the LEXUS FLAGSHIP. At one point, you even had to give a non refundable deposit, just to be placed on a waiting list to purchase a new one because of the demand. The 2004 LEXUS LS430 was around $70,000, if I remember correctly. In 04, that was and still is a lot of money for a car. The car I’m referring to is actually my Mothers car. She purchased new and still drives this car, with very little issues. The car is now around 19 years old and my Mother is 83. As her Son, I try to help with her car among other things. Both are still beautiful and going strong. The car is sorta a metallic WHITE w TAN guts. No wrecks and cleans up absolutely beautiful. Great Paint. Sorry for the lengthy post, Im a little excited as I just finished replacing the spark plugs due a rough idle and sluggish acceleration under a load while the Check Engine Light had started flashing from time to time. I scanned the engine and low and behold, wouldn’t ya know, a Code P0301 & P0306. As y’all may know that’s Cylinder 1 & 6, which are located on different banks of the engine, so might as well just replace all of the. I’ll stop and just say THANK YOU AGAIN FOR THIS VIDEO!
Mate, I bought the genuine spark plugs from Lexus dealer and they are totally same like yours. The Denso catalogue says SK20R11 too. We do this on this weekend :)
There’s alot of people on eBay that sell take denso products and copy the original near exactly so you can’t tell the difference if you look at the plug gapping tho it looks huge on the “new ones” compared to the old ones especially
I did this job 3-4 times on my 1uz when I had my Soarer couple years back. No coilpacks. Interesting to watch. I used to take me a couple of hours I had LPG stuff in the way that made it hard and time consuming. Had a Chaser also (1jz) and I got a spark plug change down to about 15-20 minutes.
I have a 2004 LS. I purchased 7 Denso plugs for about $7.50 each from AutoZone and one from the Lexus dealer for about $12.00. So, much cheaper from AutoZone. The plugs appear to be identical but Lexus comes in Toyota packaging, while AutoZone comes in Denso packaging.
How many miles on the original plugs? 23 yrs and 166k on mine. Function well and pulled one to check it. Looks normal for age and gap is almost = to new. Scotty Kilmer mentioned that he sees them with 200K and still OK.
Sweet, my friend asked me to change the spark plugs in his LS430 tomorrow. Very helpful, thanks! EDIT: He averages 15.5 MPG with mostly city driving (sea level, florida heat)
Interesting. I was getting 16.2 mpg when my timing was being retarded cause of bad knock sensor, same driving. Then again, 2400 ft MSL so lesser octane requirement and cooler than Florida for sure.
Hi,i have and LS430 year 02 one of my coil packs is broken and the guy at the garage said it was the 6 one,,so my question is which is the number 6 plug can you tell me please..
Hi very informative video.Im having a loud rattling noise coming out of the driver side area on my 2001 Lexus LS 430.It seems to be the camshaft.I was told If can be camshaft phaser.Can you make DIY video on it?Thank you
I bought the same "OEM" Denso spark plugs on eBay. They sure look genuine, but now you're scaring me... So did the dealership OEM Denso's make any difference?
There's no way it made a difference they are the same exact plugs. You had something else robbing your fuel mileage and it happen to fix itself or you calculated it wrong. Ebay didn't sell you fake plugs that looked the same and stamped the same. Hopefully you didn't contest the sale and do a ebay claim. Just screws the seller due to ignorance
Looking from the driver side fender, after you undo the bolt, it helps to twist the coil pack 180 degrees so the bolt hole on the coil pack points leftward away from the dipstick tube. The contacts of the connector will point down toward the exhaust ports. That creates enough of a gap to gently nudge the dipstick tube to the right and allow the coil pack to be pulled all the way out. If you do it right, you shouldn't have to struggle with this. No wiggling or anything.
I just bought a 04 ls43 .....Have you done tail light/brake light replacement .? Read on a forum you have to replace the entire light cluster because it is a led.. my light on the trunk below the reverse light is out ?
That’s one of prime reasons I bought 2001 with old fashioned bulbs. Tech is cute but it’s more complex, complicated and comping your wallet. “Keep it simple Lexus”
Biggest disappointment with the 3uz is because of the shitty engine cover they didn't bother to make the engine look cool underneath. Oh and that it has weaker rods and block.

Do 1 at a time - that way no dirt/debris can fall into the cylinder/engine
Blow out the spark plug wells first. If any evidence of oil leaks, swab them out, too.
@@wholeNwon Good point - I tried to clean out best I could but I did not think of blowing them out. Darn.
@@tombyorn8278 If the engine didn't seize and is running well, you're OK. I might replace mine some day but they're only 23 yo and only 166K on them.

a good recap of what I did 6 years ago. I almost forgot how to remove the stuffs on the passager side. this is good reminder!

Firebird Sweet denso supplies Lexus for the plugs, they are probably identical.
McGeorge Toyota has the plugs for $7.20 each, the updated number is 90080-91180. toyotaparts.mcgeorgetoyota.com
Well...did you get your MPG back...?

great help! I ahd that same craftsman light! it took a beating! early led light days surprised it lasted 10+ years!

I get 19.2 mpg average ,. 239k miles 2003 ls 430
i get 14mpg at 191k. doesn’t misfire but hoping a spark plug change will fix that
Looks like the gap was a little excessive on the new plugs you bought.
Thank youuu for the tutorial just did mine 05 430👍🏾👍🏾
Thanks for posting. That was useful.
my pleasure!
Anti-seize grease would have been some good insurance for the aluminum threads.
About how long did this take you? I’m not a pro but have experience. Just curious. Thanks for the video!
Might want to use a dab of anti seize on the plug threads on installation. Thanks for posing!
Denso used to say not to. Don't know about now.
Thanks for posting much appreciated
What is the link to the electronic wrench you use ?

Yep they did. I should do a comparison some day of the "denso" and denso plugs from eBAY

Great job, but soon as I seen the glove ripped I knew I would be paying the dealership too change my plugs lol
Just because your glove ripped? Hahaha
@@jessies1509 payed a 1k bill probably 🤣 for other “ maintenance “
Is the ls 430 Engine the same as a gs 430
yes it is.
Yes
how do you take the coil pack for cylinder 1 in driver side? It's blocked by dipstick and I have trouble to take it out. Thanks!
I was able to wiggle it out.
Looking from the driver side fender, after you undo the bolt, it helps to twist the coil pack 180 degrees so the bolt hole on the coil pack points leftward away from the dipstick tube. The contacts of the connector will point down toward the exhaust ports. That creates enough of a gap to gently nudge the dipstick tube to the right and allow the coil pack to be pulled all the way out. If you do it right, you shouldn't have to struggle with this. No wiggling or anything.
Thank you brother. Good video.
Is that a 10mm bolt?
Have you done your o2 sensors?!
I just bought a 04 ls43 .....Have you done tail light/brake light replacement .? Read on a forum you have to replace the entire light cluster because it is a led.. my light on the trunk below the reverse light is out ?
I know most of the ls430 04+ is LED... but I'm not too sure since I don't own one.
If you wiggle the harness connector on the brake/tail lights they sometimes come back on. Poor solder joints there.
Did you end up replacing the entire cluster or finessed it around?
That’s one of prime reasons I bought 2001 with old fashioned bulbs. Tech is cute but it’s more complex, complicated and comping your wallet. “Keep it simple Lexus”
Biggest disappointment with the 3uz is because of the shitty engine cover they didn't bother to make the engine look cool underneath. Oh and that it has weaker rods and block.
Does replacing these improve acceleration and milage?
Correct it’ll help with both I’m getting upgraded plugs on mine
Is this the same as 98 ls400?
I'm very careful about buying anything name brand on eBay because I've had too many fakes. If the price is too good to be true, IT IS!
Do we need new coil packs or can we just change the plugs?
I wouldn't get new coils unless it's misfiring.
@@theantgarage thank you
Who do we know when spark plug required replacement?
I think it depends on mileage I think you are supposed to change them every 100,000 miles. 160934 km
@Shahbaz Ali read the car manual. The manual should have a break down of maintenance schedules
What spark plugs did you buy from
eBay so we know not to buy it
I brought Denso iridium long life plugs whats your thoughts on that?
Original are platinum not iridium. And platinum last longer. Iridium my eye = hype.
They were the originals for my '98 LS400. Warranty was 110K mi.
@@daffyduckphd my 2006 gs430 uses iridium oem. Iridium it’s the best
Gap the plugs?
Alfred E. Neuman no need with the Denso he did use
No.

Can afford Snap-on tools but can't afford OEM spark plugs???
gotta pay the snapon guy somehow
NGK are not bad.
how many total spark plugs should i change ? I want change all of them but i’m not sure how many to buy!! please comment below
8 plugs total, 1 per cylinder.
thank you!! Where can i find OEM ones for my 2003 LS430 that’s not to expensive. Can you send a link if that’s possible
Jay Gandhi autozone should got em if not just go Lexus dealer but it’ll prolly be more expensive cause dealers rob people
Toyota Dealer wants US$300 for spark plug replacement on 2005 LS430.
Really !!!!
Lexus does not recommend anti-seize. Don't do it. Otherwise an informative video.
Denso doesn't either.
Flush that brake fluid 🤭
Who keeps their spark plugs for months after changing them?
Someone who knew “too good to be true.” But did it anyway. Lesson boys, girls you get what you pay for.
I do, too.
❤️🧸❤️❤️❤️❤️❤️
This guy is delusional thinking the spark plugs are different. Hope he didn't do a ebay claim against the seller.
@mwv1_2_3 happened to my Ls430 rough idle changing my spark plugs first
