Allied Signal Platinum Plus. They run about 6 bucks apiece but that along with a hotter coil and 10mm wires they do a real good job of burning that gas and giving me some good hp over the lower end plugs. I think that they changed the name recently to Titanium Plus but the specs are still the same they came with a 5 year unlimited milage warrenty and I haven't had to replace them. I actually run the same kind of plugs in all my engines 440,360,318 and the little 6 banger in my intrepid. no complaints
