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 DOHC modular motor and are a perfect match for stock engines and engines with minor performance upgrades.

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 factory 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.

  • If you are super charged you may be running a colder plug now I would stick with that.

Do you have to retune your car after installation? Car has pro charger with 9lbs boost , long tubes, and has been dyno tuned. It also has a long list of other mods.

  • The addition of these coil-on plugs will not require you to have your Mustang retuned. Hope this helps!

    accel coil plugs

    August 24, 2012

    I bought these about a year ago and they worked fine. I felt nice power gain with new spark plugs and It really did bring the torque feeling back on my MACH1 after having a few misfire issues with the oem coils. Well these decided to fail after a year unfortunately. I purchased the GMS street fighters along with some new NGK plugs at the moment so lets hope those resolve my issue for longer then a year. I don't hear many people having issues with these accels I would recommend them just because I felt a nice difference, but you could get better for the bang of the buck.

    Accel Super Coil on Plugs for my 2003 Mach 1

    March 09, 2014

    After 145,000mi on my factory original coils, one went bad. I replaced them with a set of these Accel Super Coils along with new spark plugs. The combined new parts made a huge difference! I highly recommend these for anyone with a Cobra or Mach 1.

    Great price fix compared to Ford

    May 20, 2013

    I had the same issue on my 2004 Mach 1 that most people with a 4 valve 4.6 have had when water gets under the coil cover and floods the cylinder closest to the passenger side firewall. The plug and coil had rusted and were no longer getting any spark. I replaced the coils and plugs and have been running at full power ever since with no problems. If you go to Ford, they want close to $100.00 for each coil. Definitely grab these instead.

    I purchased these coils for my 2001 cobra and could feel a noticeable difference in acceleration. The install took 30 minutes and is easy for anyone to do. Good bolt on for decent price.
