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 Darryel Tokarczyk

If I could rate it lower I would. I replaced the intake manifold and decided to replace all the coil packs as I would still have to remove and reinstall them, what a mistake. It's been less than a week and all I've done is chase intermittent misfires. My mechanic had to come to my house three times and I spent more hours removing and reinstalling old ones than I care to admit. It's also my main work truck, so I don't make any money if it doesn't work. Finally last night after changing #1 and #3 I lit it up and no misfires hallelujah! Up to 60 miles from home and here we go again. THAT IS TRASH!
