Description
High-grade alumina silicate ceramic - Creates a stronger insulator to reduce dielectric punch-through (caused by spark exiting through the side of the ceramic).Standard plugsCorrugated ribs - Prevent "flashover" of spark, which can lead to harmful misfires and rob you of performance.Solid copper core along with NGK's high grade pure alumina ceramic enables the spark plug to quickly dissipate large amounts of heat. This ultra-wide heat range prevents spark plug overheating while providing reliable starts.Triple gasket sealing process - Virtually eliminates the possibility of combustion gas leakage back through the metal shell.Longer insulator nose - This superior design, sometimes called a "power tip" prevents loading up or fouling, even after prolonged periods of idling, or at slow speeds.Trivalent metal plating - No anit-seize required.Cold-rolled threads - Prevents cross-threading and damage to cylinder headsZinc dipped shell prevents corrosionTriple gasket seal eliminates combustion gas leakage
