2008 F-150 4.6L V8 Best of Spare Parts

Had code P0306/P0316 on cylinder 6 indicating misfire. Bought these coils and replaced all 8 cylinders along with new spark plugs. All error codes have been fixed. Interestingly, the problem was transmission slippage until I finished scanning. I just installed them so can't comment on the increase in fuel economy or durability yet. I'll sign up in a few months. I'm just glad the truck is back to normal and power is restored!

Pros
  • Pleasant to use
Cons
  • Upgradeable
