ngk plugs for sure, i'm running msd wires that seem pretty good, you wont really see any difference other than appearance, dont get to frisky with the plugs on the torque, just a little past hand tight and you should apply some antseize to the threads. the valve cover bolts dont take any torque either, thanks it calls for something like 6-7 ft lbs if that. just a little past snug will be fine. sorry but no idea on the part #
