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

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

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!

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.

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.

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