Description
The NGK Spark Plug is engineered to exceed OEM standards, providing superior anti-corrosion and anti-seizing properties thanks to its trivalent metal plating. The pure alumina silicate ceramic insulator ensures exceptional strength and efficient heat transfer, preventing overheating and maintaining optimal performance. Triple seals are incorporated to eliminate leakage, guaranteeing a secure and reliable connection. Corrugated ribs further prevent flashover, ensuring consistent spark delivery. At its core, a copper core efficiently dissipates heat, preventing pre-ignition and ensuring long-lasting durability. This resistor-type spark plug with a platinum electrode tip and a 0.7 mm spark gap optimizes combustion for enhanced engine performance and fuel efficiency.
