Spark Plug Recommendations - Stage 2

[Cam.CL.S7]

Just wondering what you all suggest as far as plugs go for a stage 2 car. One step colder or OEM?

[Dasquade]

Personally i would go for the "one step colder/race plugs" for NGK. You could still go with the oem ones but better go one step up.
Just wondering, just like the "recommanded" oil change interval, if plugs shouldnt be changed sooner (oem's are normally 60.000km good...lol). I would say 20.000km...those cheaper ones (forgot name) are even recommanded to be changed ever 10.000km (or you get a change the porseline/white starts to break off..and you do not want that in your cilinder!).
*just my view on it...

What about stage 1? Should we stick to oem or do the one step colder as well?

About to do my service for 65k... Any recommendation on NGK (94460) PFR8S8EG Laser Platinum Spark Plug?

Although APR has recommended Denso IHK24 spark plugs gapped at .024" with our cars (and what I'm running now), more folks are switching back to the newest OEM RS7 spark plugs. Part# 079-905-626-M which replaced 079-905-626-G. These should work well with Stage 2 and Stage 3. I'll likely switch to them soon, as I've been experiencing an uptick on the misfires that are being logged by my car.

I changed mine out a month or so ago when I went stage 1. Originally went with the Denso IKH24s but had an insulator fail on plug #4 and had an uptick in misfires as well.

So I swapped them out for the RS7 plugs (079-905-626-M) and gapped them down to .022 and things have been much better since.

You are correct. I just went and double checked the packaging and mine are the latest 06k905601M as well. For some reason I thought otherwise. In any case these have been working much better for me than the Denso IKH24.

[Cam.CL.S7]

Thank you for all the feedback! Sounds like I’m going with the OEM RS7 plugs with PN ending in M

[i8snitches]

Assuming this is just for the 4.0T engine... Curious for those with A6 Stage 2 what spark plugs used...

At stage I right now with OEM plug. No issues. About to have 35K mile service done and it includes the plugs. Believe a NGK plug is the new Audi plug. Will be checking on that. If info is correct, I am having the NGK put in. I run NGK's in my other vehicles I have modified and they are excellent.

[Ghost2112]

I'm running the new NGK's and they are absolutely perfect aside from a slight twitch in the idle.... I HIGHLY recommend them for APR stage 1 or 2 tuning.

Oh and FYI, APR dropped their recommendation for Denso's a while ago after a bunch of us experienced tons of cyl 5 misfiring...

Ugh, wish I knew people were having issues with these. Now they will just be $100 paperweights for me.

I agree run the same ones on my stage 2 APR with DP's.

Been running great on these plugs gapped to 0.024.

Any DIY for plug replacement?

1.8T Spark plug guide
*Edit - Note: This spark plug guide is for the 1.8T motor. 2.8 V6 guys will find this info not so useful.

So i have gotten many spark plug PM's so i decided to put all the info in one spot. so lets talk plugs.


Plugs for the Passat fall into 3 categories stock, chipped, big turbo

Stock, stick with the stock plugs, stock gap and you are good to go, upgrading the plugs on a completely stock engine provides no gains at all. Stock plugs are either Bosch F7LTCR, or NGK BCP6ET or NGK PFR6Q

Chipped here is where things can get tricky, most people have good luck with stock plugs stock gap and things are fine most of the time, but if you start to get misfires, or stumbling it might be time to change the plugs to something a little bit colder. You can get away with a one stage colder plug such as the Bosch F6DTC or NGK BKR7E using the stock .028 gap and things work fine. If you are modified past just a chip such as exhaust, FMIC, testpipe, intake, or other things like bumped timing and you still have misfires or stumbling it might be time to close the gap a little bit to .026

Big turbo plugs, here is where things get fun stock plugs no good, one stage colder like above work but you need to tighten the gap down to .024 to get not to misfire the Bosch F6DTC or NGK BKR7E are a good choice and work fine once you tighten the gap down. Or even step down to 2 stages colder using the FR5DTC


Plug numbers
