The NGK Laser Iridium Spark Plug represents the pinnacle of ignition technology, designed for modern, high-efficiency engines that demand the absolute best in performance and longevity. This is the official Original Equipment (OE) standard plug for many manufacturers, engineered to deliver unparalleled stability, ignitability, and fuel economy.

Why is it a must-have? Unlike standard plugs, the Laser Iridium features a dual precious metal design: an Iridium tip on the center electrode (up to 6 times harder than platinum) and a Platinum disc on the ground electrode. This advanced combination ensures a super-fine, concentrated spark and guarantees an extended service life of 80,000 to 100,000 miles (approx. 128,000–160,000 km). Experience faster starts, smoother idle, reduced emissions, and superior anti-fouling performance with this forward-thinking, high-performance component. Upgrade your vehicle maintenance and unlock the full potential of your engine with NGK.

Key Features

• Dual Precious Metal Design (Laser Technology): Features a laser-welded Iridium center tip and a Platinum pad on the ground electrode, providing even wear and maximizing lifespan.

• Superior Ignitability: The ultra-fine Iridium tip (0.6mm diameter) requires less voltage to fire, delivering a stable, powerful spark for instant starts and quick acceleration.

• Extreme Longevity (OE Standard): Engineered to meet Original Equipment quality standards, offering a significantly longer replacement interval (typically 80k-100k miles) than standard plugs.

• Enhanced Efficiency: Optimized spark concentration leads to a more complete combustion, resulting in improved fuel economy and lower harmful emissions.

• Anti-Corrosion Protection: Features a Trivalent Metal Plating on the shell for superior anti-corrosion, anti-seizing, and excellent durability.

• Reliable Heat Management: The high-grade alumina silicate ceramic insulator and copper core ensure optimal heat transfer, preventing overheating and maintaining a consistent temperature.

• Anti-Fouling Performance: The thermo-edge design on the center electrode helps burn off carbon deposits, maintaining a clean plug for stable idling.
