Ruthenium HX High Ignitability; Pre-Set Gap: 0.032"
NGK Spark Plugs is introducing the latest technology in high ignitability spark plugs to the automotive aftermarket: NGK Ruthenium HX. Today's efficient engine designs create more power while using less fuel and this has shortened the life of traditional Iridium and Platinum spark plugs. In response, NGK's patented Ruthenium technology is used for maximum durability and performance in newer engines where efficiency is demanded.

Features & Benefits:
  • DFE (double fine electrode) and PSPE (projected square platinum electrode) tip designs. DFE maximizes ignitability while reducing emissions for low heat engines, and PSPE provides the best ignitability and service life for high heat (typically turbo and supercharged) engines.
  • Superior oxidation resistance and enhanced blistering/anti-peeling to provide the most optimal durability at high temperatures in various driving conditions.
  • Advanced high-ignitability technology that provides more complete fuel burn than other precious metal spark plugs, resulting in quicker throttle response, smoother idle, and better cold starts.
This spark plug is pre-gapped, but may require minor adjustments with a Spark Plug Gap Tool / Feeler Gauge to match your engine's specifications. For proper engine performance, gaps should be within 0.004" of OE-Recommended value.
