The tip is swivels and a mess of different-sized extensions. 10-Minutes per corner, 10-minutes setting up (removing the battery, intake, washer fluid tank), 10-minutes reinstalling extras, 5-Cleaning up. 10MM, 12MM short socket, 3/8 spark plug socket, 2" extensions is a must + longer 4", 8" extensions and swivel. Angled 12MM wrench for passenger rear coil pack (turnable wrench that angles for me).
Get a 8” piece of hose and slide it over the spark plug and thread them into the heads instead of using the spark plug socket then all you have to do is tighten for final seat. Can’t cross thread that way either. I’ve used this method servicing outboards for the last 30 years👍
I was going thru a video to change my spark plugs and brother you saved me because I had no idea about closing the gap on the spark plugs thank you very much man I have 2012 Sti 🙏🙏
I’m doing mine at 28k but I’m looking for these exact spark plugs and everytime I put my car in it keeps saying it doesn’t fit. How come? 2019 STI as well.
That was also a concern of mine as well but good question. They will work on 04+ STis and some wrxs but because they are temp range 7 instead of stock (6) they show up non compatible):
I know this video is old now, were you stage 1+ in this video? I’m currently stage 1+ & I’m trying to figure out if I should run these same spark plugs
@@Autofreakgarageone last question would it be okay for me to run the same spark plug gap .028 if I’m not tuned by Brentuning? I’m currently on the Cobb stage1+ tune
The AOS is a PITA. I was going to DIY but after going over the instructions, watching install videos, and realizing I didn’t have the equipment to do it I took it to the local shop. If you have the time, knowledge, and equipment then go for it lol
Put these in today and getting misfire error. Finding out that 2019 and newer models are now gapped from factory at .024 instead of .030 like before. Im guessing this is where the issue is
Haven't heard of that change, but make sure everything is properly in place or you didn't crack a plug. Do not over tighten the plugs as they can crack and cause this issue.
Eternal, get the NGK 5245. I’ve tried the the 2309 and gap to what my tuner recommended and always got random miss fires. Switched to the NGK 5245 and never had an issue. They are 1 step cold and should be pre gap to .24.
Im about to change my plugs on my STI right now. I had the one step colder because I got a etune by brentuning but he recommended oem. So i returned and got oem so will see how this goes
I keep seeing conflicting information on fitment, Crawford says these will work for a 19 sti but on ngks site it only shows Mitsubishi and this stays the same when checking other sites? So do I put this into my 19 sti? I’m running usually 19.5 lbs of boost but the fitment verification has me hesitating
@@shooky1092 I find a lot of STI parts in general fit / work with most years, and tons of sites have weird incompatible/not listed years etc. Its quite a hassle sometimes to figure it out especially when theyre hiding part numbers lol
@@Autofreakgarage I was planing when my battery dies IDK if it's were I live but I change batts every 2 to 3 years so I figured a lil weight and space savings wouldn't hurt . Anyway thanks for your vids really helpful.
Thanks for the tips Mission accomplished doing the spark plugs the only problem I’m having is I can’t get the passenger window down from the drivers side any tips ?
just finished up doing mine this morning and now the hill assist light is on??? any thoughts? ive tried turning it off via the traction control button method but no luck
Hmm haven’t had that happen to me. Disconnecting the battery can make the car a little loopy at first. I’d try driving around a bit to see if it goes away.
@@Autofreakgarage I did do the job on a pretty steep incline of my driveway so maybe it threw some sensor out of wack. Hopefully the car will sort itself out
I'm at 100k and I haven't change my plugs .. how bad am I ruining my engine? I'm just waiting for this weather to open up a lil so I can changed them Finaly ..
That engine bay is super clean 👍🏼.. yes I will this weekend .. I just had my timing belt replaced at 98k and I told the mechanic also do the spark plugs while your at it and he said he forgot all about it 🤦🏻♂️.. didn't charged me for the spark plug so that's good ..
Eyyyyy appreciate the shout out 🙌🔥

Dude I can't focus on anything besides how clean your engine bay is. Nicely done.

That’s my trick lol

I didn't see you add anti-seize lubricant on the spark plug's threads. Would you recommend using anti-seize or is it no longer needed?
Wouldn’t hurt to throw a tad on, but the original ones I took off didn’t have it and they came off no problem.
My 2019 STI has 23,000 miles so far. I plan on spark-plugs around 35K mark. My car is bone-stock just a bolt-on catback exhaust.
Do it sooner than later!

Yes stage 1+ at this time. Both tools are linked in the description.
@@Autofreakgarage thanks for the fast response man I really appreciate it.

love how you take care of you're STI, are you gonna install a AOS, or are you fine without it ?
Yes I have an aos and cylinder 4 cooling mod going on the car next.
The AOS is a PITA. I was going to DIY but after going over the instructions, watching install videos, and realizing I didn’t have the equipment to do it I took it to the local shop. If you have the time, knowledge, and equipment then go for it lol
@@Autofreakgarage Nice can't wait for the video of the Aos, btw any problems with the oil thus far?
No issues
@@Autofreakgarage Great feed, honestly i think if every wrx owner takes care of this car like you do, wrx won't have a bad rep.

Do i need to adjust the plugs with the feel gauge like you did?
Yes, I would check and make sure they are all gapped the same.
Do you have the link to the torque solutions gap tool? I don’t know what the thread pitch is for the spark plugs

My first time on my 2018 FXT which has the FA20 took me 2 hours. Passenger side was easier than driver side for sure. And my hands are large.
Man, chris from Bren is super helpful. Helped me figure out that I blew my cat out.
Was reading the amazon reviews and said they were counterfeit any thoughts on that?
Is a pro or E tune needed for one step colder plugs? I keep hearing mixed things.
Doesn’t matter. If you are over 18lbs on either, one step colder is recommended.
@@Autofreakgarage gotcha thanks!

They fit on all ej’s
That’s what I thought who knows why different sites say different things

Are you planing on changing to smaller battery?
No plans. No reason to.
@@Autofreakgarage I was planing when my battery dies IDK if it's were I live but I change batts every 2 to 3 years so I figured a lil weight and space savings wouldn't hurt . Anyway thanks for your vids really helpful.
is it normal that your peak psi will be reset? maybe because of the battery? and do i have to tune it again?
Yes. Anytime the battery resets, your mpg and peak boost will be reset. No you do not need to retune it.
@@Autofreakgarage okay thank you so much.
Very off topic lol but what do you use to clean your engine bay its so crisp!
Just a wipe down after each wash. Nothing in particular.
First time doing spark plugs on my 2020 sti gapped at .22 should I keep them there or gap them at .28 like u ?
.022 is pretty tight. I would get some new ones to properly gap at the .028

It says that it won't fit a 2016 STi.
Says it won’t fit on my 15 sti…? Should I still get them?
Yes it fits any year
Hey Scoob, what spark plugs should I use for my stock 2018 Sti? Really appreciate it
ua-cam.com/video/bWOfw-0dW10/v-deo.html
Did you run these throughout your whole ownership? Even when you were at 400hp?
Yep. Same plugs I ran on the many power levels I was at.
@@Autofreakgarage and you ran a .028 gap the whole time? No spark blowout?
Correct. Never changed from this video and never a single hiccup.
I'm at 100k and I haven't change my plugs .. how bad am I ruining my engine? I'm just waiting for this weather to open up a lil so I can changed them Finaly ..
Yikes haha. I would definitely change them ASAP.
That engine bay is super clean 👍🏼.. yes I will this weekend .. I just had my timing belt replaced at 98k and I told the mechanic also do the spark plugs while your at it and he said he forgot all about it 🤦🏻♂️.. didn't charged me for the spark plug so that's good ..
Can u get these for a stock car?
Yes, I would recommend these modified or stock.
@@Autofreakgarage ok thanks you
Whats the torque spec for the spark plugs?
15.2lbs. Or tighten until gasket hits the head and turn 1/4-1/2 more.
@@Autofreakgarage thank you awesome build btw im learning allot from you 🙌🏽
Where can I buy these ?
Link is the the description for them.
just got mine and the part number is LFR6AIX
do you think i can use them?
I’m not sure. I would only use the ones with the correct part number.
@@Autofreakgarage i bought it from rock auto.
The Subaru dealership charges 300 bucks to change the spark plugs
Yes they do 🤦🏻♂️horrible
Where I live the do $1200 just for the spark plugs on the 2018 Sti
Geez the dealership was charging me $1k to do spark plugs
Yikes! Either find a new dealer or spend some time with your car and get them done yourself. Not a fun job, but beats spending $1k!
first! subie gang
Are these spark plus the same as the oem ones? I’m going to do mine but want closest to oem ones.
These are not OEM plugs
Do you know what’s the best ones to put besides the oem spark plugs ?
The ones in this video
