Didn't expect much.

Knowing coil packs didn't do much performance wise I bought one for the fuel economy. Has worked good so far. Expectation met.

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?

MrPresident

  • 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!

Push Button Start I have a remote push button start installed on my 2007 V6 4.0 Stang. Will the GMS Coil pack interfere with the automatic start or vice versa?

Jcason

  • There should be no effect to your remote starting by adding this coil. You should feel some added performance though, which I think would please you.

    Easy Upgrade

    This was very easy to install. Not counting the new plugs and wires I did, replacing the coil took me about 10 minutes all together. The most important thing to remember is the proper sequencing of the wires. Use the original you are removing for reference as they print the cylinder numbers on it. If not the sequence is simple. From top left its 1-2-3-4-6-5 going clockwise. Can't beat 4 base screws and being right on top of the block for easy access. Felt the power increase right away and have already noticed a gas mileage increase. Good deal all around.

    Great item

    I had been waiting to order a Scream'in Demon coil pack and the day I decided , the Granatelli was added to the American Muscle site,,knowning the reputation of their products it was a no brainer for the added confidence for only a few dollars more. The fit was perfect and good performance , with the Street Thunder wires and NGK Iridmum Plugs.

    Decent Improvment

    Took less than 10 minutes to install and was super easy to do. I did the upgraded taylor wires and NGK spark plugs (from AM) along with the GMS coil. I didn't notice a power gain and I haven't taken my stang to a dyno, yet! The idle has improved though and I hope to see more hp and tq gains from it once I put in the 3.73 gears, BAMA tune, and x-charger supercharger. Overall the product is only a compliment to a nice car, if you are buying this for the 18hp and you don't plan on supercharging your stang then don't waste your money, instead get a CAI and a tune.

    Great value!!

    I can't believe for the price paid how much you get out of this product!! Very easy to install only took about 10 minutes!! I can definitely feel the power gain but also the fuel efficiency has increased as well!

    A Must Have!

    I got the GMS Coil, along with the Taylor Street Thunder wires and NGK Iridium IX Performance Spark Plugs, and no regrets. Easily one of the best "bang for your buck" kind of mods you can do. Installation wasn't bad. Just make sure you take a bunch of before pictures of the spark plug wires and you'll be fine. After installing everything, my stang has a MUCH better idle. Can feel a little more power off the line, but it's really noticable when accelerating in higher gears.

    Ehh!

    I ordered this wanting to get more power an gas mileage not expecting a whole lot but every upgrade counts especially on a v6. It was an easy install (make sure to label wires when taking them off) I got this in combination with bigger spark plug wires an have had it for a few months now. It's upped my mpg by 1.5 to 2mpg an a SMALL increase in acceleration. I'd say it's worth it but only with new wires.

    I wasn't expecting much from this product, but it did give the mustang a quicker response. I only bought due to FI, but either way not a bad product.

    Waste of money!

    I bought this coil thinking it would give me more power, but when I installed the coil, my pony shorted out, so I installed the stock coil back in the car and it seem to work better, the gms coil is a waste of money, You have better chances with a stock coil instead!
