      • High Performance
      • Higher Output Voltage Than Stock Coils
      • Fits 1984 to 1995 5.0L Mustangs


      More Power. The Accel Ford TFI Supercoil makes more power then the wimpy stock oem factory coils to increase your 5.0 Mustangs throttle response, idle quality and starting power. It is a perfect match for stock engines and engines with minor performance upgrades.

      Superior E-core Design. The Accel Ford TFI Supercoil uses an E-core design to maximize the energy and voltage output over that of the factory OEM coils for more power. 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. The Accel Ford TFI Supercoil is designed as a direct performance replacement upgrade for the 1984 to 1995 5.0L V8 Mustangs.

        Instant THROTTLE response WOW!!

        My car wouldn't start! I checked spark at my MSD COIL, and it had spark for three days I tried to get my Stang started, fuel tests, timming, compression, battery checks, ignition switch,TFI, plugs, wires...... The spark that my MSD COIL put out was a dull orange spark. So I finally checked the primary side of the coil and it was outside the specs by a full ohm, that was enough for me to buy this ACCEL COIL, and VRRROM INSTANT THROTTLE response WOW! Never ran better, even with my MSD box. Great coil. My MSD COIL which never let me down, was ten years old. So I can't say anything bad about MSD, but so far I really appreciate that instant THROTTLE response and smooth power all throughout the rpm range.

        I bought this item as an upgrade for the original coil mostly for the appearance factor and any benefits I could gain from a higher spark no complaints and very easy to install

        Definitely helped!

        My 27 year old Fox had the stock coil. I was having some rough starting issues and loss of power at the upper end of the RPM's. This Accel coil help with both. Very easy to install. I still probably need to time the motor again, but it was a noticeable change. Next upgrade will be the TFI itself.

        Looks good and works like a champ.

        Fixes the lack of spark to your car. Much required if your coil is broken.

      I have a 85 SVO with stock TFI ignition system. The stock coil requires a ballast resistor. Does this also require a ballast resistor or should it be bypassed/removed?

      • This coil would still need the ballast resistor for your SVO.

      Is this CA legal? Will it require a C.A.R.B. decal?

      • This is California legal and will not require a decal as it is not going to affect smog testing.
