High Performance Ignition Coil 8 Pack -Upgrade 15% More Energy For Ford F-150 F-250 F-350 4.6L 5.4L V8 CROWN VICTORIA EXPEDITION MUSTANG LINCOLN MERCURY Compatible & DG508 DG457 DG472 DG491 (YELLOW)

I purchased these to replace all the coil packs on my 2001 f150 with a 5.4 l engine. I had a miss that had developed when the engine was in high gear at about 45 mph. It would develop when I would press down on the accelerator at that speed and the engine would start to miss before it shifted down to pick up speed. The reason for the miss was that, after I remove the old ones, I found I had used too much dielectric grease inside the boots on my previous installation with another brand. I installed these with absolutely no issue, other than it takes about 2 hours in the driveway under normal circumstances. Just remember to use a THIN amount only on the inside of the boot lining, but don't fill the boot where it will occlude the tip of the spark plug that comes in contact with the coil pack spring-- otherwise you risk developing an ignition miss a couple hundred miles after installation. I've used these for about 600 miles since installing them and the truck has run absolutely excellent. I'm very pleased with the performance, quality, and price along with the included warranty and 1-800 number that is included if there are any problems with them to contact the manufacturer.

Thank you guys for a great and affordable part that really works. I really appreciate it

Arrived next day as described. Neat professional packaging. Great value for the price. Durable equipment and fitment guide made it easy to purchase the correct product for me vehicle.

Not much to say, they're run of the mill Ford ignition coils. They work so far, I've had them on my 2008 Ford Crown Victoria for about a month now without issues. The price is both the best and worst part about them. I'm still a little hesitant to 100% recommend them to everyone beyond a shadow of a doubt, I will say that they do feel better than the aged coils I had before. Only time will tell whether or not these are any good, but for now I'm still holding onto my old coils just in case.

In 2020 I purchased this exact set of coils for a 2001 Ford F-150 for the 5.4 l engine. Roughly 5 years later and I have yet to have one fail or otherwise cause issues. I will purchase these again without hesitation in the future. No issues with fitment or the install either.

Awesome.Correct fit.

The package looks great on my messed up porch
