Latest Ruthenium HX technology for modern engines

NGK Ruthenium HX spark plugs represent an advanced solution for the automotive aftermarket, utilizing the latest technological advancements in ignitability. Modern efficient engine designs generate more power with less fuel consumption, significantly reducing the lifespan of traditional iridium and platinum plugs. In response to this challenge, NGK's patented Ruthenium technology provides maximum durability and performance in new engines where increased efficiency is required.

Maximum durability and combustion efficiency

The use of ruthenium alloy allows for optimal wear resistance at high temperatures in various driving conditions:

• Urban cycle: stability during frequent stops and starts.

• Highway driving: maintaining characteristics under prolonged loads.

• High RPM operation: reliability at full throttle (up to 5000 RPM). Ruthenium HX plugs provide more complete fuel combustion compared to other precious metal plugs. This results in faster throttle response, smooth idle, and easier cold engine start.

Innovative tip designs

The Ruthenium HX series uses two of the most advanced high ignitability spark plug tip designs:

• Double Fine Electrode (DFE): maximizes ignitability while reducing emissions for low-heat engines. This patented design is recommended for naturally aspirated engines.

• Projected Square Platinum Electrode (PSPE®): provides the best ignitability and long service life for high-temperature engines. This design is ideal for turbocharged and supercharged engines.

Highest manufacturing and quality control standards

All NGK spark plugs undergo rigorous testing procedures to ensure perfect fit and performance. Manufacturing is carried out at ISO 11565 certified facilities. The technological process includes:

• Laser precision: the gap between electrodes is measured by laser throughout the production cycle.

• 360° welding: central electrodes are positioned with the highest precision using a circular welding process.

• Extreme testing: products undergo thermal shock tests at temperatures down to -40°F and mechanical vibration tests.

• Stability: combustion pressure tests confirm high operational stability with minimal dispersion of indicators.

Compatibility with vehicles

Ruthenium HX plugs cover over 93% of vehicles from 2005–2018 with high ignitability capability. This set is specifically designed for use in the following car brands:
