I just put in new ngk's (br7ek Something like that i dont have them infront of me)and gapped them correctly to.027
and now my car is accutally slower under full boost
I looked the stock plugs and i could not believe they were gapped a .025
Also i am running Buschur Stage 2 at 21 psi

I think i am just going to put the stock ones back in
or should o gap them to .025 also?

 

higher boost = u should have a smaller gap. br7es should be fine at .025-.026


they come .026

 

i thought they come gapped higher than .026?
