Very wrong plugs. Chrysler and Champion developed a dual plat plug for this application and I highly recommend that specific plug in this application. The Bosch plugs are only plat on one side of the spark. Remember, the 3.8 fires from center electrode to ground in one plug and then from ground to center electrode on the consecutive firing plug.
