    These are the OE plugs for the 2010 JK 3.8L , pay close attention to the heat range on the other plugs. my Jeep has a lean burn Economy Mode, that requires a hot plug to get the power in lean conditions. I tried a set of autolite Double Platinum plugs which cost more than the Champions to my surprise i lost a lot of low end power and began shifting in and out of overdrive on net so steep hills, the AutoLite plug is a much cooler heat range. I put the Champions back in and all the power came back, and no shifting out of overdrive, I learned my lesson Champion is the OE plug for this motor for motor and emission design.

    Pros: It works the best under all conditions

    Cons: Cant really think of any
