Description
Gain Up to 35 HP. Gain up to 15HP on naturally aspirated 'Stangs and up to 35HP on forced induction Ponies with the Granatelli Motorsports Coil On Plug Upgrade Kit. Your weak OEM coils don't deliver a strong enough spark to your plugs to ensure you're getting the most power possible from your engine, so a set of GMS coils is a great addition to both stock and modded engines.

Up to 400% More Voltage. Your stock coils deliver 20,000 volts, versus the GMS coils which are rated at 60,000 volts. And this kit features a no-resistance connector cable design so all of that voltage is being delivered where it counts.

Complete Kit. This complete kit includes all hardware necessary for installation including the 8 coil packs, connector cables, and stainless snap lock plug connectors.

Easy Installation. Upgrading your coils is easy with this kit, which is OBD-II safe and a direct replacement for your OEM setup. You'll enjoy more power, improved throttle response, and even better fuel economy with an hour or less install time using basic hand tools from this GMS Coil Plug Kit.

Application. The Granatelli Coil-on-plug upgrade kit is designed for 1999-2004 4.6L V8 two valve Mustangs including the 1999-2004 GT and the 2001 Bullitt.

Do not BUY!!!!

First off you are spending the most money possible for coil packs that have to be modified with a hammer (per GMS instruction) to make the ropes fit the 2V application. Yes they have a life time warenty

Do you need to modify your tune? I have the 3 tune Bama chip and would like to know if it needs to be retuned if I installed these. John.

  • You wouldn't need to have your Mustang retuned with the installation of a new coil pack. Hope this helps!

    Do not BUY!!!!

    First off you are spending the most money possible for coil packs that have to be modified with a hammer (per GMS instruction) to make the ropes fit the 2V application. Yes they have a life time warenty which I have used twice and have not been able to run my car at the dyno to get a whp number. This is a CRAP product! I wish I never bought them, and oh yeah after the second time warrentying these items they STILL DO NOT WORK!!!! if you are going to buy any aftermarket coils MDS of the accels work just as good with little to no problems!

    These are a "CRAP" shoot

    I brought a set of these back in 09, not from AM. They were a pain in the anus to assemble. You should not have to assemble a $400.00 electrical component with a hammer (as per instuctions). My 02 GT came to life with these cops and felt like you just hit the button on a 100 shot. Three days later they started to CRAP out one at a time. Finally enough is enough and replaced them with with MSD and never looked back. Its a shame that something that felt that good ain't worth a plug nickel

    These are not ordinary plugs

    I hesitated in getting these plugs after reading bad reviews of them everywhere but I am glad I got them. I have just installed them and tested drive the car. Engine runs much smoother, acceleration is quicker and seems to have improved fuel consumption. These are not ordinary plugs and plug and play isn't that easy. It took me 2 hours to install these to make sure every coil plugs are properly clipped onto the spark plugs. You have to first removed the boots to inspect every coil that the spark plug clips are tightly crimped on the steel wire and use a plier to crimp them if they are loose. It is best if you have a spark plug handy so you can test fit them for tightness and length before you install them. Also when installing, do not force them into the hole. If the clips do not connect with the spark plugs properly you may have misfires down the road. Just gently move the coil plugs around until they clip onto the spark plugs. Besides the little complication and precaution installing them, this is a great product and I totally recommend it.

    Great coil packs

    I read a lot of bad reviews about these plugs but I was in the market for new ones since my other aftermarket yellow coil plugs all went bad in a few months. I decided to buy these because it says they will work great for supercharger applications and that's what I have. Very easy to instal with no problems and after about 6 months never had any problem. My engine seems to run better but I can't prove it into next Dyno time.

    coil packs

    This has been my worst auto parts purchase ever, having one dead on install and was told I would get a replacement "never did" then had a second one go out then the nite mare to remove them with their poor quality crimped on connectors that came apart on removal had to go in with needle nose pliers to get them out and now have them in a box and just going to ship them back to grantelli so I find fault on them and american muscles customer service, and most likely not use either again,

    Granatelli Motor Sports Coil On Plug

    I just installed these bad boys on my 2001 roush stage 2 with vortech super charger and good God a gain of 36 horses, throttle response definitely is much better, quick and easy install, add these and denso iridium plugs and you got a great combo.

    STOP HATING AND DO YOUR HOMEWORK!!

    For those retards buying these coils and thinking that with a stock tune you'll be able to see gains....FAIL ON YOU!!! I have had these coils on my 2002 GT for over three years now on three different engines. My original with 137,322 miles w/100 shot. Second engine, completely stock N/A...ran to 4005 miles and then I flooded it in a huge puddle, and finally my latest build, .030 over, forged 9.5:1 compression for about 5300 miles now...N/A. Total mileage with no problems around... ~ 60,000 miles. All with a Diablo Sport Predator tune. If you would take the time to make sure the connections to the plugs were set right, then you'd be thrilled you purchased these. If you half assed it, sorry but you've wasted your money. I would buy these over and over again. Also, I dont want to brag but this is all coming from a guy who ran an optima battery for close to 9 years.
