Spark plug Autolite or Denso

I've used Autolite plugs in the 2.0's I've owned for over 20 years now because I think they work the best of the ones I've tried with this engine.

Hondas are notoriously picky about the plugs being Denso.

I’ve used denso IK20TT in whiteblocks and they work very well, may need to re gap if you have some boost raising shenanigans going on

I've never had any issues with Denso plugs, so I recommend those :)

I would also like to leave a comment here about having success with an autolite AR52 plug. Same exact thread size and identical reach as the OEM torch plug.

Autolite or Brisk plugs with stock gap.

I have a 05 with Edelbrock SC, 11 pounds of boost, and E85.

I replaced the spark plug with an Auto Lite spark plug. Engine light went away but still runs rough and misfire on acceleration.

If you used auto lite spark plugs that is almost certain the problem.

autolites are some of the worst spark plugs, grab some NGK iridium’s and it should be fine

I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.
