NGK Laser Iridium Spark Plug 93476 SILZKAR7E8S iridium spark plug for Jaguar Land Rover

NGK Laser Iridium 93476 SILZKAR7E8S Iridium Spark Plug for Jaguar Land Rover

The Laser Iridium Premium series spark plugs from the Japanese manufacturer NGK are a high-tech component of the ignition system, specifically designed for modern Jaguar and Land Rover engines. The combination of precious metals — iridium on the central electrode and a platinum pad on the side electrode — ensures maximum wear resistance and stable spark formation in the most extreme operating conditions.

Technological Advantages of the Iridium-Platinum Alloy

The use of an ultra-thin iridium tip reduces the voltage required to generate a spark, significantly easing cold engine starts and reducing the load on the ignition coils. Laser welding of the electrodes guarantees assembly precision and high resistance to temperature fluctuations and chemical corrosion in the combustion chamber. The platinum insert on the side electrode minimizes electrical erosion, maintaining the inter-electrode gap unchanged throughout the spark plug's service life.

Compatibility and Application

These spark plugs are an original solution for the powerful powertrains of Jaguar and Land Rover vehicles. They fully comply with the strict requirements of automakers for the quality of fuel-air mixture ignition, which directly affects fuel efficiency and adherence to emission standards. The extended threaded part and special anti-corrosion coating of the body ensure reliable fixation and easy removal during scheduled maintenance.

Recommendations for Selection and Replacement

When selecting spark plugs, it is necessary to strictly follow the vehicle's VIN code and the manufacturer's technical regulations. The use of NGK 93476 spark plugs is recommended for gasoline engines with direct injection, where the precision of the ignition timing is critically important. Replacement should be carried out with a complete set (4 or more pieces depending on the engine type) using a torque wrench to comply with the recommended tightening torque, preventing thread damage and ensuring proper heat dissipation.

Usage Method

The spark plugs are installed in the engine's spark plug wells after checking the cleanliness of the mating surfaces. Each spark plug is equipped with a protective cardboard tube, which should be removed immediately before installation to avoid accidental damage to the central electrode. The product is supplied fully ready for operation, with a pre-set factory gap that does not require additional adjustment.
