Hey guys, replacing my stock plugs w/ some NGK Iridiums and was wondering what gap size I should use with my vortech kit. Any input would be appreciated, thanks

 

my mechanic said
"eeeeeeeeeeh about that much"

but I think 35 is correct

 

A range of 0.32 to 0.40 is acceptable. They come gapped to around 0.40 I believe. I would avoid adjusting the gap if it's in range. The electrode is thin and extremely brittle. If you even touch it, you can break it right off.
