Thats what im looking for, higher perf pulgs, since im sure the OEM are out dated since its a 8+year old car.
Have you replaced your spark plugs before? if so, what did you do for your gap with the plugs, did you go 0.32, since we both have 4.2s. when i read the 55k service forum it didnt mention the 4.2. Im thinking its a smaller gap like 0.30.
