Bought two of these for our 2004 Ford Explorer V8 4WD. We had an issue with the car missing on rainy days. Would get a service engine soon light and it ran terribly. Picked up a OBDII device here at Amazon and downloaded the application called Torque for my Android phone (Free version). the OBDII port is under the dash on the drivers side. The first OBDII code we saw indicated a misfire in less than 1000 revolutions of the engine from start and the second code identified the cylinder that was missing. Lots of info online to help with identifying the meaning of the codes.Replacement is simple for most cylinders on our vehicle. A couple of the cylinders have some obstructions. #2 for example is a little tougher but not that bad. The Coil will flex, so you can usually get it on without much effort.Carefully remove the wire clip on the old Coil. Use an 8mm socket to remove the bolt securing the old Coil. Pull the old Coil out note the orientation. Slide your new Coil in. Press down firmly to make sure its on the plug. Line up the bolt hole and use your 8mm socket to secure the new Coil. Don’t over tighten. Reattach the wire clip. Done.Fire up the engine and take it for a ride. You may need to clear the old error codes using your OBDII device and App.We had two Coils causing the engine to miss. It’s been a couple of months and so far it’s been running great.Happy that I could resolve this and not pay a mechanic hundreds of dollars for an EASY 30 minute repair.

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!

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!

In 2015 my 2002 Ford F150 started to miss underload. I bought a set of these and 7 years and 100,000 miles later they are running like new. I see all the wanking about side arc etc etc but I have not experienced any of that. Additionally, this truck is a work truck with various drivers and of course daily abuse. Buying another set for my E350 Utilimaster.
