Hey guys
I bought these plugs for a while, but didn't install it till recently.
I thought it was gapped correctly so I installed them. I took the car for a spin and everything ran smoothly, it had better throttle response than my old one.

So the next day, while I was driving to work, all hell broke loose. My engine started missfiring (only when I boost). So I concluded the plugs are probably gapped incorrectly.

Not sure how many of u use or have used these plugs.
I have a cobb ap stage 1, what should the gap be?

Thx

sounds like they came gapped to big, and your blowing out the spark basically...

few minutes in google indicates they come pre-gapped at 0.045,
replace or re-gap to 0.028
