140032 SuperCoil Ignition Coil - Yellow - Individual

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!

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.

Installed on a 99 Ford Expedition EB w/ 4.5. Engine back to life with full power. Fuel economy increased about 10%... LOL on this truck that's about 16mpg so every ounce counts! Mechanic said these are good coils... could not come near Amazon price but installed for labor... took about 4 hours. Hint... most shops and large chains will have two prices for the same job. One price near $800 bucks labor is to install new coil packs. Another price near $400 bucks labor is to install new plugs. Pay for the plug job... throw the mechanic $50 and have him swap out the coil packs which have to be removed anyway to install the new plugs. On some trucks the coil packs are easy to get to. On the Expedition they are a PAIN. Yea could have done it myself but would have taken me 2 days to get to the rear coils. Worth every penny to have a pro do it. So far so good. Will update if there are any issues with these. Early yet... so far about 1,000 miles and no issues.

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!

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.

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

Coils fit perfectly and work perfectly. I have a supercharged mustang and the only change felt is the throttle response is much better. The car feels like it has a little more torque.

The good news is the coils arrived clean and shiny. The bad news is one coil failed after four months and only 1100 kilometres. The real bad news is Amazon only offers about a one month warranty. Given their low price, I can live with one failed coil if no others go for at least two years. The original Motorcraft coils lasted almost 16 years and were still working when I replaced them at 150,000 kilometres just to be on the safe side as I was replacing the 10 spark plugs anyway. Given the difficulty replacing coils and spark plugs at the back of the Triton V-10 motor, I will use Motorcraft coils if another of these Accel COPs fails. Update Nov 25, 2016: The engine in this 1999 V-10 Ford Superduty started missing at idle and moderate loads at 60 to 80 kmph; the scan tool and Picoscope showed intermittent missing on cylinders 1 and 6, much more so on cylinder 6. The engine PCM showed no trouble codes. The remaining eight cylinders showed 0 misfires. As mentioned above, I had already replaced one failed coil in January, 2016, using the spare Accel I purchased along with my first order of 10 Accel coils September, 2015. After the first failure in January, 2016, I immediately bought 5 Motorcraft DG508 coils in case of more failures. Good thing. I just now (Dec 7) replaced the two failing Accel coils with the DG508 coils and fixed the misfiring problem immediately. Doing this outdoors at minus 30 degrees celsius is no fun even though cylinders 1 and 6 are easy to get to. Reading the many many reviews on these coils, it seems that the bad ones come in batches. If you experience one failure within a few months, it is almost inevitable that you will have several more coils fail within two years at best. This vehicle, in the last 4 years, is driven less than 5000 kms per year and seldom under heavy loads. Failures this often in Canadian prairie winters can be dangerous and is simply unacceptable. I will stick with the Motorcraft coils even though they are over twice the money. The original Motorcraft coils lasted 16 years under all kinds of loads in Alberta winters and a few Arizona summers. I cannot take a chance on Accel coils. I changed my rating from 2 stars to 0 but Amazon does not allow 0 stars, so 1 it is.
