NGK DILFR6J11 Laser Iridium Spark Plug Part No. 92491 (1 Pcs)

Description

NGK 92491 DILFR6J11 Laser Iridium Spark Plug – Ultra-Premium Dual Precious Metal

Restore your engine’s peak performance, eliminate cold-start hesitation, and maximize fuel efficiency with the NGK DILFR6J11 (Stock #92491) Laser Iridium Spark Plug. This ultra-premium plug is engineered to exact original equipment manufacturer (OEM) standards and is highly sought after in Sri Lanka as the factory-fitted specification for extremely popular Japanese hybrid and petrol commuter vehicles.

The Dual Precious Metal Advantage (Laser Iridium + Platinum)

The DILFR6J11 represents the pinnacle of spark plug engineering. It is designed with a laser-welded, ultra-fine Iridium alloy center electrode paired with a platinum disc welded to the backside of the ground electrode.

• Exceptional Longevity: The high-melting-point iridium center and wear-resistant platinum ground electrode minimize gap erosion. This allows the plug to perform reliably for up to 100,000 miles (160,000 km), maintaining a stable, hot spark throughout its long life.

• Optimal Hybrid Ignition: Lowering the electrical voltage required from your ignition coils, it prevents hybrid transition misfires. This guarantees smoother engine startups, consistent acceleration, and stable engine idling.

• Superior Construction: Features high-grade alumina silicate ceramic to eliminate electrical flashover and a triple gasket seal to stop combustion gas leaks.
