    Review & Install Video

    Hey everyone I’m Justin with, checking out this Accel super coil on plug kit for all 2011 and up Mustang GTs. Accel’s been in the performance ignition game for over 40 years and continues to produce parts that aim to squeeze every ounce of horse power out of your car. This coil on kit is designed to give your new 50 motor a spark that is 10-15% stronger than the OEM coils. A stronger spark means a cleaner, more complete burning of fuel which means more horse power. So we want to see what kind of improvement these will get us but before we go install them, we want to get a baseline number down from our modified 2011 GT back there. Our 2011 GT is already equipped with abo s 302 intake manifold; Ford 90mm throttle body and a JLT cold air intake. Our baseline run on our modified 2011 gave us 379 horsepower, and 329 ft/lbs of torque. So now let’s change out the stock units in favor of the Accel coils. Install is very simple and should take you about 30 minutes using standard hand tools, these replace your factory coils so everything is completely plug and play. Now that we’ve got the coils installed let’s do another dyno run to see the difference that this kit makes. So with the Accel coils installed our modified 2011 GT made 384 horsepower and 333ft/lbs torque. This means a gain of 10 horsepower and 9ft/lbs of torque throughout the curve over our baseline. The Accel kit install easily and is a great compliment to any performance mods you might already have, or any performance mods you might do down the road. On our 2011 GT we were able to pick up 10 horsepower, and 10ft/lbs of torque throughout the entire curve, which is very impressive.

    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 5.0L Coyote engine. They 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 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.

    Application. This set of eight Accel Super Coil On Plugs are designed as a direct performance upgrade for the 2011 to 2016 GT and Boss 302 Mustangs equipped with the Coyote 5.0L 4 valve V8 engine.

    Application Note. These Accel Coil On Plugs are designed to fit the Coyote 5.0L engine that have a coil harness that features a Red Tab and Ears on the connector. 2016 Mustang owners will need to confirm the style of coil harness before ordering, as Ford made an electrical connector change on the 5.0L engines built after 2/23/16.

        will this work with a 2012 624hp ford racing supercharger? will this effect a the supercharger at all or does the supercharger not have much to do with the coil

        • the coils will work just fine on your supercharged mustang. it being supercharged makes no difference. if you are running higher boost levels this will help keep the spark from being blown out.

        Do these fit on a 2017 GT or did something change from 16-17 making these not fit?

        • No, The Accel Super Coil On Plug Kit - Yellow for the 11-Early 16 GT, BOSS Mustangs will be specific for these years only. The reason will be due to the wiring harnesses. These Accel Coil On Plugs are designed to fit the Coyote 5.0L engine that have a coil harness that features a Red Tab and Ears on the connector. 2016 Mustang owners will need to confirm the style of coil harness before ordering, as Ford made an electrical connector change on the 5.0L engines built after 2/23/16.

            Smooth idle

            I have been chasing a random misfire and my mechanic suggested hew COP and plugs which was an upgrade I was planning on anyway. Idle at start up is noticeably smoother than before. Can't honestly say any increase in power but its possible as I haven't pushed engine yet as the pesky CEL didn't go away until I had replaced the Camshaft Position Sensor so its hard to say which change was more responsible for better performance ( my $ is on the CPS).

            Very dissapointed.

            Can't say I felt any significant performance gain. Can say that I had two of these coils fail in under a year of use on a street driven car. And that only driven to cruises and shows. Definitely recommend against wasting your money on these coils.

            Accel SuperCoils on a BOSS302 w/Trackey

            The A c c e l Super Coils are impressive. That simple statement is backed up by data logging their performance over the course of a few days. Air Fuel Ratios changed by half point to lean out the RED KEY and acceleration improved. I cannot write full review because t r a c k e y is not appropriate and a c c e l is not appropriate. lol

            Worked great at first, with a smoother idle and what felt like a little more pull. After about 8 months one died on me and I bought a replacement. Then a month later another one died. Switched them all back to stock. They are just too unreliable.

            Bad warranty

            I'd love to give this product a great review, however I'm finding it difficult. I purchased my set of plugs in Feb '13 for an everyday driver '12 GT. Infrequently do I drive my car really hard. This past week my check engine light came on and informed me that my 7th cylinder was misfiring. ...move forward past all the troubleshooting, I found that the COP was the problem after putting the stock plugs back in. I called AM, the customer service agent was good, he tried to see if he could just send me one to replace it but it wasn't an option for him, he suggested calling Accel in hopes they'd do the right thing and replace it or at least offer a new one at cost or reduced price.... that didn't happen. Apparently they only warranty this product for 90 days and they aren't willing to do anything for a customer after that. After putting the stock plugs back in, I can definitely notice a difference, the plugs work.... but for how long? Not long enough with no warranty and a company that doesn't really stand behind their product.

            Easy install. Noticed an immediate difference, idle was a lot smoother than with stock coil plugs, also seemed to warm up a little quicker. Not sure about performance gain, but definitely a worthwhile upgrade.

            Who doesn't want more spark ??

            The install on this kit was quite easy. The hardest part it removing the clip that connects the wire on top of the coil. Take your time and be careful or else you might break a clip. Only tools needed is a 13mm socket and wrench to remove strut tower brace. Remove PVC valve and oil cap , then coil covers. The coils will be exposed with the wire and clip leading to the coils. I noticed increased throttle response and mpg .... No bull mpg has increased due to car being more efficient with combustion.

            I have a Roush Supercharged Mustang and put these coils in about half a year ago. Last friday my check engine light went on misfire in cylinder 4. The Accel coil went bad and i put back in stock coils and check engine light went off and runs great. Not worth the headache of buying these.

            Nice Addition to Performance

            Heard the Pros and Cons on these - but had to try them to see for myself. I'm no mechanic - but these were so simple to install -anyone who can work a screwdriver can install these. Installed in less than 2 hours - had a hard time with one connector - but other than that - these were simple to install. I noticed a difference as soon as I started my Mustang. The engine purred better and the tach was smooth. I took my stang out on the road and noticed that the engine seemed to run better, the performance seemed stronger! I'm glad I purchased these! My GT Mustang deserves the Best and these baby's delivered! Thanks AM!
