I use AUTOLITE 75s or AC 44s I put a set of champions in my street car and it ran like crap , champions in my opinion are junk I put the old autolites back in and it ran better with plugs that were used for over a year with no problems. NGKs work great for my honda but they didnt last long in my ponchos.By the way Gach thanks for the great deal on the AUTOLITE 75s !!!!!!!!
