its a S2 running 16 psi.

i was advised that NGK's - BCR 8ES were the ones to go for. and that they should be gapped to 24.

the plugs must be right as they are the same as the old plugs coming out. but im not sure if the gap is right as its still a little hesitant on boost when its bogged down.

anyone confirm what the best gap should be with that much boost?

thanks

 

I'd run the standard gap of .8mm
