A new style spark plug has been released as a running change for use in the 2004 model year 2.4L engine. The new spark plug is more resistant to possible cold engine carbon fouling.
The new style spark plug is now recommended and preferred for use in all 2004 model year vehicles and all prior model year vehicles that are equipped with a 2.4L engine. See above table and verify correct engine sales code.
NOTE:
To eliminate concerns of a possible high secondary ignition voltage flashover, caused by a thermal set of the ignition cable spark plug boot(s) to the old style spark plug (RE14MCC5), install new ignition cables when replacing the old style spark plugs (RE14MCC5) with the new style spark plug(s) (RE16MC or LZTR4A-11) for the first time.
