The ignition coil is a crucial part of your ignition system. It's function is to convert the 12 volt power of your vehicle's electrical system in to 35,000 or more volts. This produces a high intensity spark at the spark plug which then ignites the fuel in the cylinder. Coils in general will wear out over time. This will cause a misfire condition. In engines like this with one coil per cylinder you can diagnose a coil by putting a timing light on each one to make sure it is lighting the light consistently.

Great Product
My vehicle was jerking under light acceleration at 40 + mph and the new ignition coil packs solved the problem! I replaced all 8 as it's cheaper in bulk.

Great value
Truck was bucking under light acceleration around 45-50 so bad coils replaced all 8 and so far no bucking and no engine lights. Great price considering 1 coil alone can range from $45 to $90. Will update on how long they last.

Finally fixed my truck!
I have been dealing with my 2005 F150 engine having a skip or miss for about 4 months. I thought it was my transmission but when I started reading about others having the same issue online, I saw where the ignition coil was the problem with most of the F150's. Most of the sets of 8 coils were $200+. I saw these at 1/3 the price of others and decided to try them. I watched 1A's "how to" video. My son and I installed them on Saturday morning in less than 1 hour and WOW!....no more hesitation in my engine! I have about 100 miles on these coils and it runs like new. 100% satisfied!

Worked perfectly
Worked for my 2004 f50 5.4. I was concerned because they were not the motorcraft coils. But they work great so far.

Do I need to replace spark plug cable too?
Joe S on Sep 8, 2015
BEST ANSWER: There is no spark plug cable. This is electronic ignition. The coil packs replace the distribuator that used to be on old systems.
