Set of 4 Iridium Spark Plugs NGK (90565) DILKAR7D11H for Nissan Qashqai Teana X-TRAIL ROGUE

Technological Superiority of Iridium Alloy

The NGK Laser Iridium spark plug set is a high-tech solution designed for modern power units with increased requirements for spark stability. The key design element is the center electrode with a tip made of the precious metal—iridium. Due to its extreme hardness and high melting point, engineers were able to reduce the electrode diameter, which allows for a powerful discharge at lower voltages. This ensures a rapid cold start of the engine and trouble-free operation under extreme load conditions.

Maximum Service Life and Component Protection

The use of a platinum pad on the ground electrode in combination with an iridium center minimizes electrical erosion. This design guarantees the maintenance of the factory spark gap throughout the entire operation period, preventing misfires. The ceramic insulator possesses high dielectric strength, eliminating the possibility of current leakage to the shell. The outer metal plating of the spark plug protects against corrosion and the chemical effects of aggressive environments, facilitating the subsequent removal process during scheduled maintenance.

Combustion Efficiency and Environmental Performance

Optimized spark discharge geometry promotes more complete and rapid ignition of the air-fuel mixture. This is directly reflected in the dynamic characteristics of the vehicle: driving smoothness is increased, idle speed is stabilized, and throttle response is improved. Efficient fuel combustion also helps reduce the load on the catalytic converter and decreases the content of harmful substances in the exhaust gases. The presence of a built-in resistor with a resistance of 5000 Ohms protects the vehicle's electronic systems and multimedia equipment from radio frequency interference.

Compatibility with Vehicles and Engines

This set is a direct equivalent to the original Nissan part 22401-1VA1C and is intended for 2.0-liter gasoline engines of the MR20DD and M5R series.
