Pilot Automotive Nitrode Spark Plugs

Pilot Automotive Nitrode spark plugs feature a unique, patented neutral electrode placed in-between the center and ground electrodes, arcing the largest unimpeded spark into a combustion chamber. Introducing such a spark into the engine cylinder ignites your fuel more completely and efficiently, producing greater power, less emissions, and better fuel mileage. These plugs are the world's most efficient spark plugs, made with an exclusive proprietary ceramic. This unique ceramic is over 10 percent harder than any ceramic used today, resulting in the best anti-fouling plugs available. The sparks also employ a copper core center electrode, and feature rolled threads (not cut). Show Less
