mountainman Posted June 17, 2012 Share Posted June 17, 2012 I would say either champion #412 (oem plug) Or NGK 7252. I love ngk plugs and put them in everything. But i know many swear by champions for jeeps. Even before i had mine ive heard that for years. Link to comment Share on other sites More sharing options...
cruiser54 Posted June 17, 2012 Share Posted June 17, 2012 NGKs and Napa/Belden wires will be fine. What about the cap and rotor? You don't need fancy wires and you don't need cheapie wires. Link to comment Share on other sites More sharing options...
Pete M Posted June 17, 2012 Share Posted June 17, 2012 copper plugs and middle-of-the-road wires. :thumbsup: can't go wrong. Link to comment Share on other sites More sharing options...
cruiser54 Posted June 17, 2012 Share Posted June 17, 2012 Cap and rotor with brass terminals. Clean your throttle body and check your intake manifold bolts for tightness. Link to comment Share on other sites More sharing options...
