Ruthenium spark plug NGK 94122 LFR6AHX-S Ruthenium HX 1 pc

NGK 94122 LFR6AHX-S Ruthenium HX Spark Plug 1 pc

Technological Breakthrough in Ignition Systems

The Ruthenium HX line from NGK represents the pinnacle of engineering in ignition components. This model is based on the use of ruthenium, one of the rarest and most durable metals of the platinum group. These spark plugs are designed for modern engines with high compression and turbocharging, where extreme reliability and spark stability are required. The ruthenium tip of the central electrode has a significantly higher melting point and oxidation resistance compared to iridium, ensuring the retention of factory performance parameters throughout its service life.

Maximum Efficiency and Economy

The LFR6AHX-S spark plug is designed using patented DFE (Double Fine Electrode) technology. The thin central electrode and specially shaped ground electrode with a platinum insert ensure the fastest possible flame front propagation.

• Improved Ignitability: Minimizing energy loss on heating the electrodes allows the spark to ignite even lean fuel mixtures more effectively.

• Fuel Economy: Stable combustion reduces gasoline consumption and the volume of harmful emissions into the atmosphere.

• Cold Start: Confident ignition at sub-zero temperatures and reduced load on ignition coils.

Premium Level Durability

The use of precious metals in the "ruthenium - platinum" pair virtually eliminates electro-erosion wear. The spark plug body design includes triple-layer chrome plating and a special coating that prevents thread seizing to the cylinder head and protects against corrosion in aggressive road environments. The high-density ceramic insulator prevents voltage breakdowns, ensuring the delivery of all charge energy to the electrodes.
