You flowing enough boost for those plugs?

 

There 1 step colder I figured 1.5 bar with kelford 272 cams should be enough no?

 

22-23# of boost is about what I am running as well. You'll want to gap your plugs somewhere between .022" to .028". I usually run a .024" gap.

You could go wider than .024" if you do mostly highway driving. Conversely, you may wish to tighten the gap down below .024" if your car sees a lot of stop-and-go traffic with extended engine idling, or if you were ever to switch over to Meth injection and higher boost levels

 

Should be. Call your tuner. The guy I talked to recommended going colder at about 400 whp but I didn't research that further.

 

.024 works well for me at 23psi on IX turbo (93 oct)
