Where are the sparkplugs on a 2004 Jeep Wrangler?

Answer 1

The spark plugs are under the coil rail on the passenger side of that AMC inline 6. It's that long black thing that takes a 12mm socket to remove. Make sure you DO NOT use platinum spark plugs or even truck plugs as that old design chugs along perfectly well with good old regular plugs. Be sure to use dielectric grease on the plug tops where the rail attaches to them to help in combating corrosion and aid in the spark. If it has that Neon four cylinder, then you can use whatever plugs you like or can afford. I hope this helps and God Bless! -slant6guy w/ '83 Ram D150 SWB: Cliffordized:)
