[Red Mustang Gt 46]

Taylor makes a good set of wires for the 4.6...FRPP's have a history of not lasting long at all. (from my experience as well as others)

BTW, your not going to feel any difference in performance if your car runs good already...and change them plugs.

Plugs are another story, everyone has different experiences...but I can tell you that NGK V power plugs are used by many Mustang performance enthusiast. Plain old copper plugs work well also, don't waste your cash on Bosch +4's or +2's...they are a WASTE.

Good Luck
