Review on Revamp Your Ford Lincoln Mercury'S Ignition With CarBole Pack Of 8 Straight Boot Ignition Coils by Greg Muin

Purchased these coils after reading many reviews good and bad, was worth a shot for the price. Installed all 8 of these in my 2006 ford f 150 5.4. My truck ran like a Champ! but only for 42 days. I was heading home from work on the highway doing about 80 mph when all of a sudden as quick as a blowout my engine just started shaking vibrating. So i let off the gas the shaking went away then the hesitation sputtering started happening, oh boy i'm back to square one. Turned out to be cylinder 7 misfire. I took the coil out and reinstalled it to see if that was the problem, "I really wanted these coils to be the much cheaper answer" and still had misfire. So i installed one of my old coils and my truck is running great again. I would only recommend these coils as a cheap fix if your going to sell or trade your car in.
