I installed new OEM spark plugs and wires Saturday 4-4-2020. Manual says change out at about 100,000 miles but after reading several posts I decided to change them. Order stock champion and Mopar wires. None of the wires broke off but took an effort to remove. The #3 plug tip had completely burned off and #6 plug wasn't tight in the head...it wasn't running bad or anything. I bought it new in 2011 and it's never been worked on. Milage was 81,799. I pulled the wires and tray from drivers side to passenger side and pulled a cord thru with harness. Put wires in tray one at a time and taped to cord and Shazam . They pulled thru from pass side to drivers .

#3plug tip was burned off. #6 plug wasn't tight in head.
