I was wondering if anybody knows what to gap the NGK T6 on a 2003 Silverado 5.3..... Im about to install a wet kit.... i have heard .35 what should it be???
Most people say .35 as a general gap but myself and CRAZYCUTER4.8 have found that with his 4.8 and when I had a 4.8 and now with my LS1 that .50-.60 is working the best for us!
