The NGK 2842 Laser Platinum Spark Plug - PJR7A is engineered for high performance with its dual platinum surfaces that ensure long-lasting durability and stable ignition. The laser-welded platinum electrodes minimize wear, resulting in superior idle stability, improved fuel efficiency, and reduced emissions. It features trivalent metal plating for excellent anti-corrosion and anti-seizing properties, along with corrugated ribs to prevent flashover. The pure alumina silicate ceramic insulator provides strength and efficient heat transfer, while the copper core aids in heat removal. Triple seals are included to prevent leakage, making this spark plug a reliable choice for optimal engine performance.
