Guy at the track swears by them adding more mph to him trap. (Maybe 3?) On a 14 gt500 he has em on. Anyones thoughts on em? See a ton of 03 cobra guy selling theirs on here about all I can read which is why I made this post.
Perfect. Ty!They may add a slight power gain, but all of these aftermarket COPs are ridiculously expensive and notoriously unreliable. They tend to fail when they reach the warranty period. Not worth the time and effort. I had a set on my supercharged F-150. Never again.
