Review on 🔥 MAS Ignition Coils DG511 + Motorcraft SP515 SP546 Spark Plugs | Ford Lincoln Mercury V8 V10 4.6l 5.4l 6.8l | 3L3E12A366CA 5C1584 C1541 FD-508 UF-537 (Set of 8) by Tyrell Hudson

My 2005 Ford F150 FX4 had some engine misfire problems and since I bought it I've had ignition coils all the time. During the last coil that was manually replaced, I was advised to replace all the plugs and that the store would ask for at least $400 (plus extra if some of them broke). So I bought this kit and my friend replaced all of my coils and spark plugs and it runs so much better! Fuel economy has also improved. My last fill was 15.4mpg, which is a lot better than the 10 or 11 it got before I changed it.
