Only plugs to use for a Chysler product.
Over 125,000 miles on OEM plugs. This will keep that factory fresh performance for your MOPAR.

Not so Good
Replaced OEM plugs (also Champion) at 35,000 miles per maintenance schedule. These platinum plugs should last to 100K miles. First one failed upon installation. Check engine light through code P0301, misfire #1 cylinder. Took back to Advance for an exchange. Another one died around 10K miles later. Now the third one P0303 code misfire #3 cylinder. I have Denso, Autolite and NGK plugs in my boat and other cars. No issues. Looks like Champion quality has deteriorated.
