I have champion iron heads on my gn wanted to replace spark plugs with something other then auto lights this is the plug champion recommends do you guys run anything spacial or just ac delco
My car ran strong with NGK BPR6FS plugs gaped at .028" when my car was at 440 RWHP. Once I started making over 500 to the wheels theyed cut out at high boost. Now I run AC R43TS plugs gaped at .028".
Happy spooling.

My gap was .027-.026 w/ the AC R42TS at 28-30psi it worked for me.
