NGK Laser Platinum Spark Plugs offer OEM-grade ignition precision with enhanced durability for high-performance engines. Built with dual platinum surfaces, these plugs ensure slow electrode wear, extended service life, and consistent spark stability, making them ideal for daily-driven performance vehicles and demanding operating environments. The fine-wire platinum center electrode supports efficient ignition and clean fuel burn, promoting smoother idle, reliable cold starts, and improved throttle response. With a copper core for rapid heat transfer, pure alumina ceramic insulator for strength, and trivalent plating that protects against corrosion and seizing, these plugs are engineered for long-term performance. Triple sealing prevents leakage under high compression, while the extended projection design enhances combustion efficiency and emission control. A perfect solution when maintaining OEM heat range and factory performance is essential.
- OEM Heat Range for factory-spec performance and reliability
- Dual Laser-Welded Platinum Electrodes for long life and stable spark
- Fine-Wire Platinum Center Electrode (1.0mm) ensures efficient ignition
- Extended Projection Tip promotes clean combustion and smooth idle
- Copper Core improves heat removal and prevents knock
- Pure Alumina Ceramic Insulator for high strength and excellent heat transfer
- Anti-Corrosion Trivalent Plating prevents seizing and enhances durability
- Triple Seals ensure no combustion gas leakage
- Resistor Design (10k Ohm) reduces electrical interference
- Gap: .043” (1.1mm)
- Heat Range: 6
Torque Specs:
- Cast Iron: 10.8–18 lb-ft
- Aluminum: 7.2–14.5 lb-ft
- Longevity: Approx. 40,000 miles
- Quantity: Sold individually
- Warranty: 60 days
