Review on Bravex 8 Pack Curved Boot Ignition Coil - Boost Ford Lincoln Mercury 4.6L 5.4L V8 Performance by 15% with DG508 C1454 C1417 FD503 Upgrade (Yellow) by Quinton Wonsley

Installed myself in a 2006 F150 5.4 liter V8 with 125,000 miles. It took about 2 hours. The truck stops at a speed of 40-50 km / h. They fixed it and now the truck is working great. I changed the spark plugs after about 90,000 miles, so I knew the misfire wasn't coming from the spark plugs themselves. They arrived well wrapped and boxed the next day and appear to be of high quality. The entire 8 coil pack was $70 and the local auto parts store was asking over $200 for the 8 coil pack. They've only been in stock for about a week but so far so good.
