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

The resitor plugs and later the wires where design to reduce AM radio noise before FM radio where put into cars As far as firung faster or lasting longer electricity travels at the same speed as light and radio waves, 186,000 miles per second so the plugs probally fire in the same time, + or - one or two nanaoseconds, not enough to worry about As far as longevity I don't know, I usually change the plugs long before ther worn out The good ignitions of today, stock and race ones, and unleaded gasoline will make a spark plug last 50,000 to 120,000 miles before it is missing or causing problems I haev used both in my cars with no noticeable differences Any restance in the primary ignition circiut will make the coil make more voltage before it will fire the coil to the plugs, which is not a bad thing, especially if you have a carb that is rich at idle or on start ups
