i was told 2 things to stay OEM on...plugs/oil filter
sorry, for this question but which brand are the oem?
The only issues I have heard from using the Motorcraft plugs is the breakage issue when removing them. While most have seen no problems with using Champion, E3, Bosch, etc, these are the ones you see having intermittant problems with rough idle/misfire due to bad plugs. I have always heard using OEM plugs is your best bet, and I just bought a set to install this weekend. Wish me luck!!
