    Hey everyone Justin here with AmericanMuscle.com, and I’m checking out Accel’s super coil on plug kit for all 99-04 Mustang GTs. Accel has been in the performance ignition game for well over 40 years, and continues to produce parts that aim to squeeze every ounce of horse power out of your car, whether it’s a weekend cruiser or an all out drag strip monster. These Accel coils give your modular motor a spark that is 10-15% stronger than your OEM coils by using a specialized magnetic steel core, optimized winding, resistance and turn ratio, this basically equates to a hotter, stronger spark, which gives you more horsepower and better fuel economy. This is extremely important to those of you looking to get the most out of your motor, but may be dealing with old faulty OEM coils, possibly resulting in a misfire. Alright I know what you’re thinking, get to the good stuff already, gotcha. Ultimately we want to see what kind of improvement these coils will make on our GT, but before we do that let’s get a baseline number down and see what we’re working with. So our baseline run on our 2000 GT gave us 221 horsepower and 261 ft/lbs of torque. Now let’s get those stock coils out of there and install our Accel units. Install is very simple and should take you about 30 minutes using standard hand tools, I will advise you to disconnect your battery first and then go ahead and remove your intake tube, that way you can access everything a whole lot easier. You will need to grab a 7mm socket, and remove each one of your coils individually replacing them with the Accel units. So now we have everything installed here back at the shop we’re going to run the car once again on the dyno and see the improvements this kit made on our GT. So with our Accel coils installed we put down a total of 220 horsepower and 267 ft/lbs of torque, now while we didn’t see any peak horsepower gains from the coils, we did manage to pick up 7 horsepower and 11 ft/lbs of torque throughout the curve. Let’s face it, getting old stinks, especially when it comes to critical components pertaining to your ride, your factory coils are a great example. As they age they have a tendency to fail, resulting in loss of power, worse fuel economy, and ultimately a poor running vehicle. This kit from Accel is a great way to make your modular motor feel young again for a fraction of the price of new OEM coils.

    More Horsepower. The Accel Super Coil On Plug Kit makes more power then the wimpy stock OEM factory coils to help produce more horsepower from your modern SOHC modular motor and are a perfect match for stock engines and engines with minor performance upgrades. Curve gains of 7 HP and 11 TQ has been seen on a Stock Mustang with a 93 Octane Tune.

    Superior Design. Accel coils feature an advanced bobbin technology, highly specialized silicone magnetic steel cores, along with optimized winding, resistance and turns ratios to delivery 10-15% more energy than the stock OEM coils. More energy equals a hotter spark that burns fuel more completely releasing all it's potential energy translating into better fuel economy and more power that you can feel.

    Application. These Accel two valve Super Coil On Plugs are designed as a direct performance replacement for the 1999 to 2004 SOHC GT Mustangs.

        What spark plugs are needed with super coils When buying super coil-on-plug kits, is a stock or stock replacement spark plug OK? Or do you need a special plug because of the higher voltage?

        • I put in factory motorcraft spark plugs when I put the coils in and it's been about 5 months car still runs strong as when I first put'm in. Hope this helps.

        Alternator upgrade needed? is it a "wise" choice, or a "must have" choice to upgrade alternator also? I do know i got a bad coil and need new ones, but if i get them and later on upgrade alt. will the new coils put more strain on stock alt?

        • I'm not sure about a "wise" choice, but we kept the stock alternator, drove 1600 miles through the mountains and had no issues at all (not "must have").

        My factory coil pack is going out and I was wondering if I can buy these to replace the factory one or do I need to buy something or upgrade anything else to make these work?

            accel super coil packs

            I sent them back my mechanic said he would not put them on his wheel barrow. I bought them because I had alot of Accel parts in the 70's and 80's and had alot of success. My mechanic said he has had to replace these parts because of failures. I bought original motorcraft parts

            I was having a misfiring issue where my car was stumbling and not pitting out full power. Changed all 8 coils and there no issue now. Car accelerates very smoothly now and does not jump like before.

            The Interceptor is alive again!!

            My son and I swapped engines in his 2003 Mustang GT Deluxe with the 4.6L Police Interceptor motor. The coil packs that we were working with were tired and flimsy. The engine was running on 5 or 6 cylinders and when we replaced these with the Accel coil packs... wow! It runs like new. These coils do the job very well. I hope they last for a while.

            This brand only warranties their product for 90 days!!! I have had mine for a year and 8 months and one is already shot. My car is missing and barely running due to them. Can’t get a replacement and they don’t sell single replacements either...

            So far so good!

            Got these when I replaced my plugs and intake manifold, had a coolant leak by that stupid heater core return line that soaked a few plugs in coolant causing a missfire when accelerating on a cold engine that went away when it warmed up and this fixed the missfire when it's cold! Can't tell a difference besides that they work.
