Spark Plugs
There are a lot of different plugs out their but believe it or not the most basic ones are best. I honestly recommend Champions for any Chrysler application. If you own the 3.0L then the NGK v-power plugs will be good also. They are a little more money than champions but have a specially designed diode with a V-shape that can vary electric paths. I overgapped them to about .44 to give a bigger spark in the combustion chamber. I do not recommend Bosche plugs, especially platinum plugs of any kind on this engine or any Chrysler engine.
