            short lived

            Used for a little over 2 years and roughly 7-10k miles until i started having horrible misfires and breaking up really bad under wot, went back to the oem 15year old coils and my car drives fine again. I was hoping they would've lasted a little longer than they did.

            Coil Pack

            Install these coil packs on my 2001 Cobra, and I notice a a positive power gain over original manufacture equipment. I would recommend this product.

            Easy fit, no issues as of yet (7 Months)

            Quick and simple assembly, adds a few KV to the Factory output for a sure-fire spark- great for wider gapped Plugs. All in all, great bang for the Buck!

            Coil pack

            Easy install and the car runs smoother and better throttle response.

            GTMS coil packs for GT500

            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

            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.

            Great Coil for the Price!

            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.

            Good deal

            Great tune up item when replacing plugs. Car idles smoother and at lower rpm. Acceleration was restored and I am happy with the price and performance.

            GMS 4v street fighter coil pack

            Worth the price. Replaced my original coil packs with these and some ngk spark can feel the engine is running a lot smoother and I no longer have a misfire during idle.
