What would be the best spark plug to use on a stock turbo.

Thanks

nice i forgot about the gap....minor details right:redface:

gap?

any opinions concerning running tighter plug gaps as boost# rise -like25# plus? when I first bought my car the gaps were set at .028".I left them alone...car runs great... Is there really much to be gained concernig gap size...?

ive heard that with higher boost it is good to close the gaps to .032" or so maybe even tighter! this will prevent the spark from being blown out or not jumping the gap. hth
