[QUOTE="TrainTrac, post: 1026765, member: 55399"] Don't waste your money or busted knuckles on anything other than OEM plugs, wires, or coil pack. The 4.0 V6 is very finicky when it comes to plugs, and most folks who've "upgraded" to something other than OEM Motorcraft/Autolite plugs have reported problems with said plugs. And personally, I had better luck with the OEM coil pack than the Screamin' Demon coil pack. I went through two of the SD packs in a three-year span and then finally put the OEM coil pack back on. I'd also installed the SD Live Wire plug wires, but honestly, I don't think they made that much of a difference. However, they did look cool!:supercool: [/QUOTE]
