    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?

    Mark2001

    • 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?

    SCFF

    • 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").

    Hi I replaced my spark plugs at 96k on my 2001 gt my car now has 97k should i replace the coil plugs? I don't think my factory ones are bad but if I can get better performance I would do it

    • Hello, JamesBT5U3342208 replacing those old factory coils is a great way to free up some power, provide you with better mileage and nail down some preventative maintenance.

      Smooth idle

      Idle was rough thought I'd give the super coils a try and wow what a difference they make. Id let smoothed out and throttle response is better. Wasn't looking for hp gains just smoother idle so not sure if there was hp gains but definitely a quality replacement for OEM coils.

      Good value

      Having put them on my 2003 4.6L, I have noticed a smoother idle and more torque, especially in 5th gear on the highway. Installation was pretty easy, and the shipment arrived very quickly. Very satisfied so far.

      Accell Super Coil on Plug Kit

      It was easy to install and I noticed immediate improvement, Granted the old coils were on their way out, but I am a fan either way. I would buy them again or suggest them to a friend. You could easily install new coils in less than an hour if everything goes well for you. Make sure you do not over tighten the bolt! The inserts in the plastic intake manifold for the 4.6 PI engine that the bolt screws into can be broken loose if you significantly over tighten.

      Could probably go with a cheaper set but these work out fine as a stock replacement in a standard bolt on 2000 gt.

      Do not buy a waste of money

      This coil pack sucks doesn’t give you more HP than OEM I bought this like 18 months ago and I have to replace them now since I’m getting a P0354 code with scanner, warranty it’s only one year from manufacture, so don’t waste your time and money go for OEM

      2002 Ford Mustang Gt

      Very awesome coils. Had trouble deciding whether I should buy the MSD coils or Accel coils but I’m happy I bought these. I’m sure the MSD coils are good too, but my friend had the Accels on his GT and it fixed his misfire so why not buy them, especially for the price. It fixed my horrible misfire too! Thanks American Muscle!

      Cool ignition coils

      I bought these and they really are at a great price. My friend and I installed them which took a couple hours and is a bit of a pain in the 02 mustang gt, if your engine bay is a bit grimey like mine haha. Well these really make the engine pop with the bright yellow coloring. I'm not sure about the performance gain but I'm sure it gave me a bit more oomph along with my cold air intake and exhaust setup and a custom Bama tune. Don't forget to upgrade your spark plugs because I blew a couple cheap ones out from revving too hard and of course it's the one under the air intake in the very back so just do it lol.

      Improved performance

      I had a miss under load conditions. Couldn't pinpoint which coil was failing. So I replaced all the coils and plugs. While changing the plugs. I discovered that the previous owner stripped out one of the spark plug holes. I was horrified ! After all was.put back together. The misfire went away. Engine runs much more smoother now. Noticed a better tone at idle. Take your time when messing around with the fuel rails. O-rings can be damaged if one is in a hurry.

      These coil ons compared to my stock motorcraft are a monster, the throttle response is instant, and it gives your engine a nice look. I would def recommends these, great bang for your buck. Very simple installation so it's a very easy mod.
