NGK UR6IX

However I think I should go colder because I get a ping in a narrow spectrum of the RPM range and I have already backed base timing to 8*

Turbo 3.1 Hybrid. '90 GP STE. T25 Turbo/Intercooled, 8.5psi, used to run 12psi before topend swap with no problems.

I've run these in both my Turbo 3.1 cars and also in my dads Turbo 3.1 GP with no problems. Haven't found anything I've liked more yet.
