Hi,anyone have anything to say about these?Part # ETP-E3-42..Pricey,but the Summit ad promises more power,mileage,100k guarantee,leaps tall buildings,faster than locomotive,yada-yada....Are they worth the extra dough?...Thanks,Jason
in my eyes no. if you have an upgraded ignition sytem (mallory, msd, etc..) then maybe. but even then im sceptical. ive seen real strong cars runnning cheapo auto lites and have 0 issues.
Just a gimmick if you ask me. I don't see how they could possibly help? The electrode is shrouded more on those plugs, so they might make igniting the mixture even more difficult. Run a standard copper plug as noted above and save yourself some money.
