stock engine, only mod is CAI from the cowl really. HL fenders, but not seeing that causing this either.That's weird. You're running the 4.0L right? All the heat should be on the driver's side. Exhaust runs down the pass side, but that is lower than where you're talking. I can't imagine anything electrical generating that much heat, without any other symptoms. Do you have the Catalytic under the belly still? Might that be heating something up that is transferring?
ya 2 mini cats on the DS and twin pipes i figure that side would be the hot side if any. main cat is still inline underneath, little tighter to the floor with the skid, but no issue i know of there. running around all that heat would/should get swept back.
