Cold-rolled threads to prevent cross-threading and damage to cylinder heads
Trivalent plating eliminates need for anti-seize and corrugated ribs prevent flashover
وصف
NGK Standard Spark Plugs are treated with corrosion resistant plating to ensure ease of installation and removal. The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating. Cold-rolled threads prevent cross-threading and damage to cylinder heads. Trivalent plating eliminates need for anti-seize. Corrugated ribs prevent flashover. High-grade alumina silicate ceramic.
