    Great Coil for the Price!

    December 27, 2012

    I got these coils mainly to fix a hesitation problem I had with my 99 Cobra at part throttle. With all the 4.6 mustangs I've had, this usually is a sign of a coil that's starting to go bad. These coils fixed the problem as soon as they were installed. I could also feel a difference in the engine. It was smoother and all around better running. I even picked up a little gas mileage. Not the most pricey set of coils on here, but these are just as good in my opinion.

    GTMS coil packs for GT500

    May 27, 2014

    Excellent fit and craftsmanship is great. Idle quality seems alot better and throttle response is good. My 08 GT500 is modded so alittle more spark is welcome with the 80lbs. injectors to help burn the fuel.Mustangs are for driving not parked!!! Check your grill emblem of that horse running.!!!!

    Does what it's Suppose To

    April 22, 2014

    The performance gain is pretty negligible for these. Coil packs aren't meant to provide any performance gain like cams or new heads, but they do fit well and were super easy to install. The engine runs a little smoother since I've added these. I did also change the spark plugs at the same time so that "smoothness" could be attributed to that as well.
