Review on 🔥 MAS Ignition Coils - Ford Lincoln Mercury V8 V10 4.6L 5.4L 6.8L 2005-2008 - DG511 C1541 FD508 Compatible - Pack of 8 by Roger King

The plugs seemed fine but after about 2 weeks of installation the truck started making all sorts of electrical codes. I really got into trouble on the freeway when I needed the power to drive and couldn't get past 70mph. removed the coils and decided to spend the coin on motorcraft coils and the check engine light went out and no more problems. After removing the coils I shook them and you could see the coil moving in the coil pack itself. I didn't think it was coils at first because I replaced all 8 coil packs and spark plugs, obviously the problem must be elsewhere. I replaced the air filter, the mass air flow meter checked the vacuum lines, it turned out that there were coils all the time. don't be like me
