New NGK Spark Plug Line Features High Ignitability Technology

The new NGK Ruthenium HX spark plug line from NGK Spark Plugs (U.S.A) Inc. consists of 25 part numbers covering over 200 million vehicles currently in operation.

Using patented precious metal Ruthenium technology, the new NGK Ruthenium HX offers higher ignitability, enhanced oxidation resistance and increased durability for today’s modern engines, according to the company.

Currently, high ignitability designs make up 52% of the OE Article mix for 2005 to 2018 model year vehicles, a number which is expected to reach 60% by 2020.

With two times the service life of the NGK Iridium IX and four times the service life of nickel spark plugs, the NGK Ruthenium HX provides maximum durability for even the most strenuous engine applications, according to the company.

Due to the metal composition and specialized tip designs, NGK Ruthenium HX offers the highest performance and life expectancy of any NGK spark plug currently on the market.

As a high ignitability plug, the NGK Ruthenium HX guarantees maximum combustion efficiency to ensure the most complete fuel burn, a quicker throttle response, smoother idle and better cold start.

NGK Spark Plugs says it achieved the high ignitability in Ruthenium HX by combining two of the most advanced tip design technologies available: Double Fine Electrode (DFE) and the first-to-aftermarket Projected Square Platinum Electrode (PSPE). DFE is intended for non-turbo applications, and PSPE is intended for turbo applications.

NGK Spark Plugs manufactures ignition Articles, oxygen sensors, technical sensors and vehicle electronics.  In addition to serving OE automotive and aftermarket customers worldwide, NGK also produces spark plugs for motorcycle, power sports, marine and small engine manufacturers. Complementary Article lines include resistor caps, spark plug wires, and high-performance cables. 

In North America, NGK is headquartered in Wixom, Mich., and maintains manufacturing, inventory, and distribution facilities in Irvine, Calif., Sissonville, W.V., and Chicago, Ill.  For more information, visit
