These right here are the best: http://www.af1racing.com/store/Scripts/prodView.asp?idproduct=1390 Amazing longevity and starting/idleing will be much better
Unless you are racing, then these give you a little more compression, thus more power (3hp approx) and are surface discharge type: http://www.ngk.com/results_cross.asp?pid=R2349-10&x=42&y=13
NGK R2349-10 (9 is a little hotter if not racing)
