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 Shane Popo

FYI -- F-150 2004-2008 if you feel a wobble at about 50 mph when going uphill that makes it feel like your transmission is slipping, tune in with new spark plugs first and replace also the coils. I asked the dealer to replace my spark plugs due to the notorious spark plug failures in this F-150 generation and the price for a tool to remove the failed spark plug matched the dealer's cost. Unfortunately, the cost of replacing the coil pack was astronomical. So I let them do the setup and hoped for the best. I asked about my old forks so I can make my own assessment. I knew I had to change coils quickly. The old spark plugs (2) were in bad shape and I could feel the wobble where there used to be a pop. I'm "old school" and "if it ain't broke don't fix it" so of course I was waiting for the misfire code three weeks later. I said I knew it had to be done, right? I just installed these coils (<50 miles on them) and they seem to have solved my misfire problem. I gave 5 stars because they fit perfectly, are several times cheaper than original parts and work. Reading smaller reviews I hope these coils will work perfectly for at least a year. I kept my old coils as suggested just in case. I will update my review if anything changes. The price was my main reason for buying because I could get all 8 coils for the price of 2 aftermarket "performance" coils. I did notice it getting a little "dizzy" on the freeway, but it was a short jump. I'll know more once I can test it with her in the spring. Winter in the Adirondacks isn't the best time to fiddle with the engine. I hope this review helps. Many thanks to all reviewers, information is knowledge. Keep the shiny side up and the rubberized side down :-)
