I have been told that MKIV's love the NGK's no matter what stage you're @. I believe the # is 3330 - pregapped from Dusty to the right spec.

Beautiful car and engine bay! I think most singled cars are using the ngk 3330's. Just play around with the gap. Probably start around .032 and see if it misses at high boost/high rpm's then go down from there. Im at bpu+ with exhaust cam gear set to -4.5 running a tight .030 gap. Idle is a little rough, but it doesn't miss at the higher rpm's with boost cranked to 1.4 bar.

I just ordered some NGK6097's....Currently I have in NGK 2978's, gapped at .32...no miss at top end and my dyno graph was very smooth, no choppy shit.
