hi all,
i was wondering what spark plugs work well for a 100 wet shot on a bolt on 93 z28,
right now i have the TR55 gopped at .05
so shouldi get the TR6 at .03 or what?
thanks

 

im runnin tr6's gapped that way and they work just fine. Havent noticed any difference in NA power also but maybe its so small it would be real hard to tell. I am also spraying a 100 wet shot

 

I personally prefer the autolites over the NGKs. 104s would be good for your application. Although TR6s would work just fine as well. I just think,(from personal experience) that autolites are less prone to fouling.
