        I installed this along with livewire plug wires, smoothed out my idle and can feel the difference in my throttle response. Also got 27 miles to the gallon on my 2 hour trip to my doctor. I think I could have gotten better mpg if I would have not had a heavy foot.

      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

      Up to 18Hp What other modifications do you need/suggest to get the full 18Hp. ?

      • This was one of the first mods I did to my pony. Really simple install. I added 2 things; Performance Distributors Livewires 10mm Spark Plug Wires and NGK Iridium IX Performance Spark Plugs . I could tell the difference immediately! I hope this helps!
