Well I got her done. The plugs were a snap. The wires were a turd. The plug wires on that 3.9 V6 had better be exact or you'll end up with one too short by just a skosh! The plug gap is supposed to be .035. They were probably .050 and yes I needed a new cap and rotor. All Chrysler part numbers including the wires. The plugs had been replaced. I bet the cap and rotor are original. 120,000+ miles.
