Spark plug 1 pc NGK 94122 LFR6AHX-S Ruthenium HX for BMW Lexus Toyota Volvo

Single Spark Plug NGK 94122 LFR6AHX-S Ruthenium HX for BMW Lexus Toyota Volvo

Revolutionary Ruthenium HX Technology for Maximum Power

The NGK 94122 Ruthenium HX series spark plug represents the pinnacle of ignition system engineering. Unlike standard iridium or platinum alternatives, this model utilizes ruthenium—a precious metal from the platinum group that possesses significantly higher resistance to oxidation and high-temperature corrosion. This allows the electrode to maintain its shape and functionality even under the extreme pressures and temperatures typical of modern turbocharged and direct-injection engines.

Electrode Design Advantages

The unique tip design ensures the fastest and most complete ignition of the fuel-air mixture. Ruthenium HX technology minimizes the "quenching" effect of the flame, resulting in more stable engine idling and instantaneous throttle response. The use of this precious metal allowed for an ultra-fine center electrode, which reduces the voltage required for spark gap ionization and eases the load on ignition coils, extending their service life.

Reliability and Durability in All Conditions

The spark plug body is protected by a patented trivalent metal plating, which prevents the threads from seizing in the cylinder head and protects the metal from corrosion. The high-purity alumina silicate ceramic insulator guarantees dielectric strength and efficient heat dissipation, preventing pre-ignition. An integrated interference suppression resistor ensures the correct operation of all vehicle electronic systems and sensors.
