Good OL NAPA
Auto parts, carrys most NGKs, priced right , too.
I had a noticibly positive difference in the seat and idle behavior over HD plugs and I am not using the Iridium.
NGK .040 gap is for stock compression, .032 (I believe) is for around 10.25. adjust slightly higher comps.
My compression is 9.6, I gap at .036 one cold from stock.
go to go
