Set of 4 spark plugs NGK 93476 LASER IRIDIUM Iridium SILZKAR7E8S for Jaguar Land Rover

This set of 4 high-performance NGK Laser Iridium spark plugs is designed for 3.0L V6 gasoline engines installed in JLR vehicles. The Laser Iridium Premium technology combines the use of precious metals on both electrodes, ensuring exceptional durability and ignition system stability under high temperature and pressure conditions.

Superiority of Iridium Alloy in Ignition System

The SILZKAR7E8S plugs feature an ultra-thin iridium center electrode welded with high-precision laser. This metal has one of the highest melting points, making it virtually immune to electrical erosion. The small diameter of the electrode concentrates electrical energy, allowing reliable ignition of the fuel mixture even with a lean composition, which is critically important for modern direct injection engines.

Platinum Protection and Engine Resource

The side ground electrode has a platinum pad that prevents metal wear at the spark point. This technical solution allows maintaining the factory-set gap between the electrodes throughout the entire service interval, eliminating misfires and increased fuel consumption. The spark plug body has a special anti-corrosion coating that protects the metal from oxidation and facilitates the removal process during replacement.

Installation and Compatibility Recommendations

The set of 4 units fully covers the needs of six-cylinder engines, such as the 3.0 Supercharged, used in Range Rover Sport and Velar models. It is crucial to use a 14 mm thin-walled spark plug wrench and adhere to the specified tightening torque during installation. Each spark plug is equipped with an individual protective cap to preserve electrode integrity during transportation. Compatibility should be strictly checked against the original Land Rover (LR032027) or Jaguar (AJ812154) part numbers.

Operating Instructions

Spark plug replacement should be carried out on a completely cooled engine. Before removing the old plugs, the spark plug wells must be cleaned of dust and debris with compressed air. New plugs from the set are installed manually until seated, then tightened with a torque wrench. It is recommended to replace the entire set simultaneously to ensure uniform cylinder operation and prevent premature ignition coil failure.
