Review on 🔥 CarBole DG508 Ignition Coil Packs - 8 Pack Coil-on-Plug for Ford F150 Lincoln Mercury, 1997-2017 - 4.6L 5.4L 6.8L - Reference Part Number: DG508 DG457 C1454 FD503 by Luke Cotton

I was offered $315 for OEM kits so I figured I could replace them a couple of times for $70 before spending $315. They were fairly easy to replace and so far I've replaced all the spark plugs there. Thanks to them, my 2000 Ford Excursion 6.8L V10 ran like new. I had fluctuations and loss of power, at 1500 rpm the car was shaking like a mixer. It cured my problems. I've been on them for 750 miles so we'll see if the Chinese parts fail before the OEM, but I don't mind working on my car and it was too cheap not to. When installing the boot on top of the spark plug, it is recommended that you first apply some dielectric grease to the boot.
