Set of 8 Ruthenium Spark Plugs NGK 94122 LFR6AHX-S RUTHENIUM HX for Toyota Lexus BMW HONDA

Maximum Power and Technological Superiority of Ruthenium HX

This set of eight Ruthenium HX series spark plugs represents the pinnacle of NGK engineering. The use of ruthenium—a precious metal with a much higher melting point and oxidation resistance compared to iridium—allows these plugs to maintain stable performance characteristics even under the harshest operating conditions. This set is specifically designed for high-performance eight-cylinder (V8) engines, where synchronous operation of all cylinders, high throttle response, and ignition system reliability at high RPM are critical.

Double Fine Electrode (DFE) Technology

The unique Double Fine Electrode (DFE) design minimizes the flame-quenching effect in the combustion chamber. The ultra-fine ruthenium center electrode, combined with a platinum tip on the ground electrode, creates a powerful and stable spark discharge. This ensures instantaneous ignition of the air-fuel mixture, leading to more complete fuel combustion, increased torque, and a significant reduction in detonation risks. The engine runs smoother, and the accelerator response becomes linear and predictable.

Durability and Protection of Engine Components

NGK 94122 spark plugs feature an extended service life of up to 160,000 kilometers, substantially reducing maintenance costs. The high-quality alumina silicate ceramic insulator prevents electrical leakage and withstands massive thermal shocks. A special trivalent metal plating on the shell guarantees protection against corrosion and prevents threads from seizing in the cylinder head, ensuring easy removal even after a long service period.

Detailed Vehicle Compatibility Table

This 8-piece set is designed for high-performance V8 gasoline engines and can also be used for full replacement on vehicles with smaller displacement engines when spare units are required.
