Awesome!

These coils are great. Runs much smoother and better performance. Beats spending $40 per coil for OEM. I recommend these for all 4v mustangs.

What Kind of spark plugs do you recomend with this product. I have a 2003 cobra with a Jlt cold air intake , a 2.8" supercharger pulley and a sct custom tune that makes 457 rwhp. Just wanted to add a little more power.

  • 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

    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

    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

    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.

    Easy install more power

    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.

    Hotter spark, more power.

    The coils make noticable acceleration increases smoother and more in tune to the engine's response when you step on the accelerator. The old original Motorcraft coils had 92,000 miles on them and didn't 'lock' snug onto the tips of the spark plugs in their tubes. These new Accel coils do. So the electrical contact to the plugs is direct. I'm happy with the way these products perform.

    2003 Mustang Cobra

    These are a great replacement for the stock coils. They fit right in place without issue. Noticed a smoother idle,and better throttle response. I doubt I gained any significant horsepower, but for the price they did what I needed them to do. Can't go wrong if you are looking for a good coil at a decent price. Now I just have to see how they hold up.

    Couldn't have been easier!

    Was getting a slight miss at higher rpm's. Cobra has 150K miles. This (and a new set of Iridium plugs) have taken care of the issue. Highly recommend this product.
