    5 Top Rated Questions

    Which coil gives out the most power? Out of the three coils AM sells, power wise they are uncomparable. The GMS can give up to 18hp more, another says it gives out 45000 volts, and the Accel has NO number to compare.

    • They all allow more current flow than stock. All the specs are very close so go with Accel coil. It's less expensive and allows just as much current as the GMS. I put the accel on my wifes V6 stang and opened the spark plug gap on the Denso Iridium plugs an extra 5 thou . It works very well. better gas mileage , More power.

    When buying the GMS coil is it recommend to buy the NGK Iridium IX Performance Spark Plugs

    • That's exactly what I did, and I couldn't be happier with the results! I saw an immediate increase in power, and saw increased savings at the pump, which I don't visit as often as I did... An inexpensive and very efficient mod, I highly recommend pairing these two items with some top notch cables too...!!! I hope this helps!! ~tim

    Is the GMS Coil pack any better than the Ford Factory Coil pack? I was told that the Factory Mustang Coil Pack puts out as hot a spark as the high priced Performance Coil packs...is that true? If so, will buying the GMS Coil Pack really make any difference?

    • The factory Ford coil is a very good piece, for very stock motors. When you start modifying, adding more fuel and air, you need more spark. The GMS coil puts out about 60,000V whereas the factory Ford coil has an output of around 20,000V. This will also be a great upgrade for any Mustang equipped with a V6. Don't forget to upgrade the wires and replace the spark plugs at the same time. More spark, more power, better fuel economy. Hope this answers your question and thanks for choosing American Muscle!

      Great purchase

      Super glad I bought this coil. I instantly noticed a lot more power and acceleration and it started a whole lot easier. This was something I added after doing a tune-up with straight Motorcraft spark plugs and wires. I have a BBK cold air intake and a BBK throttle body already on my car I was having issues with a throttle body and air mixture and I'm not sure if this solve the problem or if it was luck but after putting this coil pack on the issue has gone away.

      A little more Spark

      I installed it on my 2007 4.0 to go with my BLU Live wires and iridium spark plugs. That with my Roush cold air intake and American Thunder Muffler make a great combination..

      Easy install

      Took me less than ten minutes to uninstall the old one and reinstall the new one. No problems thusfar. Despite the ease, instructions should be included for those who aren't very mechanically inclined.

      Easy Install and Noticeable Performance Gain

      With 100k plus miles on my manual V6 it was time to change the coil pack, wires and plugs so I went with the GMS coils and couldn't be happier. The install was simple; I disconnected the battery (this isn't really required), installed the wires directly on the new pack, loosed the screws and removed the old pack, placed the GMS in the old pack's place, installed and tightened the screws. The increase in performance was immediately noticeable in all gears but especially in third. I highly recommend this as a mod or if you're simply due for a tune up.

      GMS Coil

      Had a coil pack failure so I decided to try this GMS Coil pack. Was already using a high voltage one and alone with a lot of other add on's A high voltage Coil Park is a must. I do not notice the 20 horsepower increase but start ups just a hit of the button. Getting ready for a 500 mile trip so I will see then if it really improves my gass mileage.

      2007 V6 mustang

      Ok guys and girls. I just installed this coil. It took me about 20 minutes. You need to have this on your mustang. Save the money, put it on your credit card do whatever it takes but add this on your engine, your pony will love you for it. Just FYI I also upgraded my spark plugs and performance spark wires, including body throttle and CAI from BBK, not to forget my pypes headers and pypes cat back exhaust. Ohh by the way if you really want to get a bang for your buck i recommend Bama Performance tuner. All this included you will not need a V8...my pony sounds and runs like a V8 and i do not break the bank with the gas stations. So back to this coil..i just added 14 hp in about 20 minutes. American Muscle....Thank You!
