E3 Spark Plugs Parts and Accessories

    Jeep Spark Plugs E3 automotive spark plugs utilize the latest E3 technologies to help engines operate more efficiently by burning fuel more completely. Our patented design gets the flame (or combustion process) started earlier in the combustion chamber before gas is vented off when the exhaust valves open. Although results may vary dramatically based upon piston displacement and operating conditions, increased combustion efficiency and a faster burn allow E3 equipped engines to minimize the venting of unburned (wasted) fuel.
