NGK 95125 Ruthenium HX Spark Plug

The NGK Ruthenium HX spark plug represents a premium upgrade in ignition technology, featuring a 0.6mm ultra-fine wire ruthenium center electrode that delivers exceptional ignitability and durability. Ruthenium, one of the platinum group metals, offers superior hardness and high-temperature resistance compared to traditional platinum or iridium plugs, resulting in consistent spark performance and extended service life.

Key Features:

• 0.6mm ruthenium center electrode for improved ignition efficiency
• Platinum ground electrode provides excellent wear resistance
• Trivalent metal plating for superior anti-corrosion and anti-seizing properties
• Corrugated ribs prevent flashover and improve insulation
• Pure alumina silicate ceramic insulator for superior strength and heat transfer
• Triple gasket seal eliminates combustion gas leakage
• Cold-rolled threads prevent cross-threading and damage to cylinder heads

Engineered to OE specifications, this NGK Ruthenium HX spark plug delivers optimal combustion efficiency, improved throttle response, and enhanced fuel economy. The ultra-fine wire design concentrates spark energy for reliable cold starts and smooth acceleration across all operating conditions. Backed by over 80 years of ignition expertise, NGK spark plugs are trusted by automotive manufacturers worldwide for their quality and reliability.
