I was wondering the pros and cons of non resistor spark plugs. I see people talking about interferance with electronics but in a race car situation, will it actually make anymore power in a bracket car? Are there any problems with MSD ingition boxes with them? School me if you don't mind. Thanks.

I believe all of the race plugs are non resitor so the MSD boxes, race and strret ones, should work well with either resitor or non resitir plugs. I have ran both in my Duster at the strip and on the street with no noticeable differences on the track or street I thank getting the correct timing, spark plug heat range and jetting is way more important than which type of plug

Thanks Cab. Does one last longer than another or something? If they make no power differance, why do they make them both ways? Are the non resistor plug faster to fire? Scratching my head here now...lol
