High-Ignitability Spark Plugs
Ruthenium HX™ brings the most advanced spark plug technology to the automotive aftermarket, delivering better efficiency and power for today’s engines.
The NGK Difference- DFE & PSPE® tip designs
- Superior oxidation resistance
- Advanced high-ignitability technology
- Enhanced blistering/anti-peeling
The Latest Innovation in Precious Metal Spark Plugs.
Modern engines demand more power while using less fuel, shortening the life of traditional iridium and platinum spark plugs. NGK’s patented ruthenium technology stands up better to wear to bring maximum durability and performance to your engine.
Designed for every engine.
Ruthenium HX is available in two designs to best maximize the performance of your engine.
DFE (double fine electrode) maximizes ignitability, while reducing emissions for low-heat engines. This NGK-patented design is recommended for non-turbo applications.
PSPE® (projected square platinum electrode) provides the best ignitability and service life for high-heat engines. This NGK-patented design is recommended for turbo and supercharged engines.
Iridium IX®
The improved throttle response, superior anti-fouling and high-ignitability makes Iridium IX® ideal for the performance enthusiast. Iridium’s extremely high melting point is perfectly suited to today’s high-temperature engines, delivering outstanding acceleration, fuel efficiency and durability.
- Fine iridium tip ensures high durability and a consistently stable spark
- Trivalent metal plating for superior anti-corrosion and anti-seizing properties
- Outstanding acceleration, high fuel efficiency and durability
Laser Iridium
Laser Iridium is designed alongside OEMs to meet quality and durability standards for each manufacturer. Featuring high-grade alumina silicate ceramic and fine wire center electrodes, the Laser Series brings OE performance to every engine.
G-Power®
NGK G-Power® platinum spark plugs feature a single platinum tip, 98% pure copper core and a .6 mm fine-wire center electrode for more focused sparks and better ignitability.
- Trapezoidal ground electrode reduces quenching
- High-grade alumina silicate ceramic for stronger insulation
- Cold-rolled threads prevent cross-threading and damage to cylinder heads
Laser Platinum
Laser Platinum is designed alongside OEMs to meet quality and durability standards for each manufacturer. Featuring high-grade alumina silicate ceramic and fine wire center electrodes, the Laser Series brings OE performance to every engine.
Performance Spark Plugs
NGK nickel spark plugs feature a specially designed v-groove center electrode, improving ignitability and reducing quenching. The 98% pure copper core delivers increased heat dissipation for more reliable starts and reduced risk of overheating.
- Cold-rolled threads prevent cross-threading and damage to cylinder heads
- Trivalent plating eliminates need for anti-seize
- High-grade alumina silicate ceramic
