Stupid question but i cant find a solid answer anywhere. I need new spark plugs, what brand, gap???? LNF(Stock turbo, mods: Hahn Cold intake, zzp 3 inch downpipe, zzp intercooler pipes and intercooler, 3 bar map sensors, zzp tune

 

Oem ac Delco plugs, I have mine at .030

 

Stock plugs, never anything else....trust us, we have tried them all. .032 gap, which is what they are gapped at I believe in the box. U can do .030 as well. I use .028 on zfr

 

I'm on .35 e85 25psi stock turbo on 41-108 ac delco.

 

Wait I think .035 is what they normally gapped at. So ya that's the most u should go with them. But the most important thing is that they are the stock AC delco

 

Ok thanks everyone
