ACCEL 140032-8 SuperCoil Ignition Coil - Yellow - 8-Pack

Got these for my 2001 Crown Victoria P71 CNG-powered Police Interceptor, now going on 94,000 miles and starting to growl (idle rough) from old spark plugs and COPs ("Coil On Plugs"). Ford replaced one COP and plug and it ran better for a little while, but then the rough idle came back. The dealer wanted almost $100 a COP plus labor to replace the rest of them with Ford parts, so I got these COPS from Accel for about $180 for the set of eight. I've had great luck with Accel products on my other cars in the past, and they did not disappoint me here. I paid Ford to put them in (because one thing I don't do is mess with 3000 psi fuel systems, which had to be disconnected to install the COPs). At first the Ford tech said they lacked a rubber insulator on the side of the coil top like the OEM part, but I called Accel directly in Cleveland and they assured me they would fit and work fine in my CNG car, so I went ahead and told Ford to put them in, along with 8 new Ford spark plugs. (Also the Amazon "Fits your car" pull-down at the top of the order page said they'd fit.) Sure enough, they worked perfectly, and the car now idles smoothly and has perceptibly more power. I can only assume that Ford added the insulator on the side of their OEM COPs to prevent heat damage; the Accels don't have this insulator but I'm hoping they are designed for higher performance and don't need it. Also the vertical black boots that come down off the yellow Accel COPs are noticably thicker than the OEM part, and there's no noticable static on the radio after installation. Finally, the yellow top on the Accel COPs matche the yellow "Optima" deep discharge Police battery, and makes the overall engine compartment look cooler. This car has in fact been a car show star, for it's unusual combination of Police features and CNG fuel system. Similar CNG-powered Crown Vics have been known to run over 600,000 miles, but it's a good idea to change the COPs and plugs every 90,000 miles apparently, as the stock plugs were quite worn when I replaced them and the COPs were showing signs of wear as well. At any rate, these Accel COPs are highly recommended as a cost-effective way to improve performance and keep these great CNG cars on the road using cheap, plentiful, clean-burning American natural gas!

There are excellent. I highly recommend. This is the 3rd vehicle I’ve used them on. They never have a problem or die way too soon.

The Accel coils that come in the kit are a direct replacement for the coils on the 5.4l engine in a 1999 F150. My truck has 245,000 miles and I've replaced the coils once, unfortunately with a not so good brand. The truck began to miss when sitting at a red-light and would hesitate when I'd begin to accelerate. It wasn't bad, but I did not want to chance having it stall in the middle of a street and have someone broad-side me. I bought the Accel kit and installed the coils in about three hours. If I had to do it over again, I'd pull the fuel rail to make it easier to get to the plugs in the back, especially on the driver's side. Once the coils were in the truck began to run smoother. It took about a week for the computer to adjust everything with driving conditions and varying temperatures, but now the truck idles and runs like its old self. Idle is back down to about 600rpm in drive while sitting at a red-light and 650-700 when its in park. No hesitation now and I'm not worried that it's going to crap out when traffic is coming. Too, the Accel kit from Amazon was the least expensive around. I checked Jeg's and Summit Racing and both were over $200. From my point of view, it was a good deal.

I don't normally write reviews but I'm exceptionally happy with this order. My 2004 Ford F150 5.4L was misfiring at 60-90Km/h. The dealer diagnosed a host of problems including the transmission amounting to over $2000. We live in Qatar where dealers think they can charge any amount they want and the typical customer will just take them at their word. I borrowed my neighbour's diagnostic computer (also available on Amazon) and decided to take a look myself. The computer showed the errors PO345, PO354, PO011 and PO021. We decided to start with new coils. Again the dealer wanted almost $500 for the set of 8 but I found these Accel coils for much less and they work great. All errors disappeared, engine light turned off and the truck runs like a top! The angle of the boot was different so I used the old boots. The angle of the plug at the top is also a little different for my engine model so they were a little tough to plug in but not impossible. I would suggest changing the spark plugs at the same time but give your engine a good cleaning first so junk doesn't fall in your engine. There are some good videos to guide you on youtube. Thanks!

My E250 van was starting to spit and sputter. Sometimes it would be okay, sometimes it would get pretty bad. At first I thought I got into some bad gas when traveling, as it started acting up after a fill up on no name gas. But not so. At 70,000 miles I replaced the spark plugs (2V, no problems), still spit and sputter. I thought about replacing the coils, but the price was high. Then I found this deal on Amazon for the entire 8 set of Accels and went for it. My van now runs great! The mileage increased 2 to 3 mpg, so the money I spent on the parts will pay for itself with less gas. Simple to install, but rather tight working conditions on the van. These come with new boots, too. Unplug the wire with the little squeeze clamp, remove one bolt, pull off the old coil with the old boot, and install the new one. I did use a little silicon dielectric grease on the rubber boots to help keep them from sticking onto the plug. I used a piece of wire to rub it around the inside lip. (when I removed the original boots, one or two did stick and I used needle nose pliers to pull them off.) Worth the effort, I've towed my car trailer with car, and it pulls much better.

After accepting my rough-idling as a way of life with my Ford Tritan 4.6L engine, I was pleasantly surprised... SHOCKED... when after replacing all 8 coils with this set, my tach needle sits still, almost as if the engine isn't running! I'm at 185K miles, and my tach needle used to dance up and down so randomly, sometimes so low it seems like she would sputter out and shut down, or out of the blue go so high that it seemed like I was egging other drivers to race me as soon as the light turned green. My engine never threw out any error codes, and I'm no mechanic, so I didn't know where to start with that type of problem. Many friends and family members who know better than I contributed the issue to (1) my engine having so many miles on it, and (2) it being a Ford. I only changed my coils because my #3 spark plug shot out of my engine block, so I had to do the repair and needed to replace the coil anyways so I figured I'd change them all. Autozone's Duralast coils are $59/each. These come out to less than half that (each), and even less when you purchase the set. From what I've learned, coils are supposed to last 100K miles, and throughout the years, mine have been replaced 'as needed', but my engine never ran this well! After all 8 were replaced with the ACCELL Super Coil Kit, my F150 drives like new!

I replaced the failing stock coils and some aftermarket coils I purchased with these high performance coils. The key is to replace all 8 at one time. If you have several coils failing over a two or three month period, it is more cost effective to replace them all in one shot, especially for the price you can get these high performance coils. NOTE TO LOOK OUT FOR: If your intake manifold has a water leak and is getting moisture on the coils, this can short them out. That is what was happening to me on my 2001 Ford Expedition 5.4L. My Mechanic replace the intake manifold and then I had him install all eight coils at once. My truck has 170K miles on it, and I have had coils going out one at a time over the last 30K miles. At the time I did not know it was the leaking intake manifold that was shorting out the coils one at a time, so I replace 5 or 6, one at a time as they would go out. Finally did it right and replaced them all after intake manifold leak problem was fixed. NOW, I have more power and better gas mileage. They are working great. It has been about one month since they were installed. We will see how long they last. Was getting 11.2 MPG, now getting 13.3 MPG. UPDATE: It has been over 2 years now and still going strong.

These are complete GARBAGE. I put them into service in a fleet vehicle, Ford 5.4L V8. This was a tune up to replace the OEM which had no issues but I thought it would be an upgrade. After 2k miles 2 of them failed. I could not allow them to remain on the vehicle so I went back to FORD and spent 2.5X as much for the OEM, however, there have been no issues since then. This was in April of 2014. I only now realized I never contacted AMAZON about them and figured it would be worth a try to obtain a refund of some type, even if only on 2 of the useless coil packs. AMAZON went above and beyond my expectations, no question, no arguing, simply offered to replace or refund. (I obviously took the refund) This is one of the reasons my family and I use AMAZON so much. THANK YOU AMAZON !! I am 100% Loyal.

Los instalé en un Mustang GT 2000 4.6 SOHC, llevo 5 meses y no he tenido problema alguno.

Worked great for me in my 2007 Crown Victoria Police Interceptor (4.6L V8). I can't speak of longevity yet, but the price can't be beat. The stealership wanted about $80 per SINGLE coil pack. Simple math shows these are a much better buy, even if 1 or 2 die a few years down the road. Cost me $260 after all taxes and stuff, and I got a pack of 8 less than three days later. 45 minutes of work, with my friend doing one bank of cylinders and me the other and ta-da it runs amazingly. Idles dead smooth and even at 800RPM, and no stutter or hesitation in acceleration like before. The stutter was especially bad with OD on during highway driving up slight hills (around 1200RPM), felt like a really bad transmission shudder.

Engine runs better than ever easier on gas too more power for sure

easy install, very happy

easy to install, works well . no problems with product.
