You can't go wrong with these if your looking to upgrade or replace factory plugs it's a good time to replace these with the plugs. It's a plus that these look great. ...

My old coils were pretty much toast, so when i installed them and drove for the first time i felt a huge improvement over stock. Better acceleration and pic up too.

would these cause a cam sensor to go off on 12mm plugs? I ordered the ford racing heads and installed them on my 07 mustang gt and I think these are the coilpacks you sent me and was just curious if these being on 12mm plugs would do anything differently?

Hey guys i have a 2006 GT 4.6 running stage 2 eldelbrock supercharger the car is running sweat but as its aging i have been contemplating changing the coils the car has done 90kilometers now the plugs are new when supercharger was fitted only done 1500km since fitted. My question is i am reading so many conflicting reports about only using OEM coils ate the accel coils reliable and is it worth changing to these or just waiting till old OEM ones eventually fail ????? As i have bought items from you before so i will be guided by your input. thanks craig britten

  • I have tried a few so called upgraded coils. You definitely feel a difference while driving NA, but as soon as you go into boost, all these coils fail. They don't have the power to jump the gap under boost. They are great for NA applications, unfortunately not boosted. At least thats been my experience. I wish we had options stronger coils for our boosted cars.

What are the best spark plugs for these coils?? I use this as a daily driver and need to change my plugs, but am wanting to upgrade my coils at the same time. What are the best plugs to go with these?? I have just a few minor upgrades--nothing extraordinary though.

  • I would recommend staying with the stock OEM plugs, and you can order them here from AM for much cheaper than elsewhere. These COP's provided a slight performance gain in my case, and depending on the mileage of your current plugs, you may notice a slight MPG increase as well. Also, before you attempt changing the plugs yourself, research(if you haven't already) the issue of the OEM plugs seizing and breaking off in the head during removal at higher mileages.

    Way Better Than Stock!!!

    I put these Accel coils on when changing the factory spark plugs out at 30,000 miles instead of the suggested 100,000 mile marker, and Man am I glad I did..everyone of the spark plugs had started to seize into the heads as everyone knows how aluminum and steel love each other. I didn't really expect any big difference as I have always used Accel or MSD coils in all my rides for better feul economy and power from a hotter spark, but going from a 2 second crank up to a just bump the starter start up was totally different and not expected at all. Which is why I would totally recommend these as I put them and the sparkplugs on within a 30 minute window, must faster as I had expected as well. I do recommend buying a tube of dialectric grease and putting a pea size amount in the end of the boot before sliding on the plug as they fit correctly and will prevent a future knuckle scrap as removing the factorys, the last one got me against the fuel rail.

    Definite Improvement

    The main reason i ordered these new coils were because my factory ones were failing. A lot of people told me not to waste the money on them because they wouldn't do anything for me, BUT i disagree! I dont have dyno proof of the difference (yet) but i can already feel how much smoother the car runs and pulls. I also have an O/R X which always had a raw gas smell from the car, after these were put on that was completely gone so you know its running more spark and burning more fuel.

    Fast Installation and Worth It

    Installed in 15 minutes. My Saleen Supercharger really enjoyed more spark, throttle response is better and it feels like I have gained a decent amount of HP over OEM ones. For some reason though it took me three cranks in the cold morning to start my car with these, hopefully that will go away.

    Great replacement

    I bought these as a replacement for my stock ignition coils, one of which was going bad. They went in in less than a half hour. I did not notice any performance gain. One would probably have to dyno-test to notice any difference. They look great under the hood. I ordered next day shipping at 5pm on a tuesday, recieved them at 10AM on wednesday, in CA. Way to go AM! Edit: Have been driving for a month with these and they feel great. (I drive about 350 miles a week.)

    Fast, easy upgrade

    I got these for my 2006 GT as a replacement for the stock ones. I haven't noticed a HUGE difference in power or economy, but it does seem there is a little extra power there. I also put new spark plugs in at the same time, which is probably a good combination. They look great, seem to work great and were easy to install!

    Noticable difference in throttle response. Smoother idle as soon as they where installed. I put them on with new plugs. Good idea when running higher octance fuel. They look good under the hood which is a plus.

    Smooth Surge

    These coils provided a nice smooth power boost over the stock coils. Hard to explain the power gains in words just seems to run smoother then it did stock. No doubt about the improved look under the hood. The yellow color grabs your attention and screams ACCEL which has been a proven ignition performance upgrade for decades now. Just another upgrade for my pony among many over the boring stock stuff!

    Accel Supercoil Purchase

    I wanted to upgrade the ignition system due to several performance mods (ford racing intake, ford racing throttle body, CAI, Brenspeed cams, long tube headers) and these coils are exactly what I was looking for! Install was simple and took less than an hour. I am completely saisfied with the looks and performance. The car seems to run smoother and seems more responsive since the install. I searched several web sites and the price was right on target!

    looks great, works great

    I added these when I changed spark plugs after adding a lot of other mods like CAI, Hot Rod Cams, FRPP intake, 62mm TB, and more. Car runs a lot better and the lope of the cams are more defined. Not sure how much the coils had to do with it, or changing the plugs that had 75,000 miles on them.

    These went great with brisk silver plugs and helped out with frpp cams. Plus my stock coil packs had a lot of miles and was due to be replaced anyway. So these where perfect way to tune up my car.

    Excellent Mod to Support Others yet to come....

    These are super easy to install. My install took less than 20 minutes. Instantly noticed a lot smoother acceleration as well as a much smoother idle. The coils are expertly designed and the fit and finish is awesome. The electrical connectors are in the factory location and did not put any additional stress or stretch on the connections. Not to mention, it adds a good amount of color under the hood! Definitely recommend these even as a tune up item, as they are cheaper from American Muscle for a performance unit, then stock replacements are from Autozone or any of those other parts retailers. Excellent customer service and quick shipping as always from AM!!
