NGK 93763 Ruthenium HX Spark Plug LKR6BHX-E High Ignitability

The NGK 93763 Ruthenium HX spark plug (LKR6BHX-E) is a high-ignitability performance plug built with the same OE-style technology NGK uses in modern engines. It has a ruthenium alloy center electrode and a projected square platinum ground electrode. Together they give a more complete fuel burn, which helps with throttle response, idle smoothness and cold starts.

Key Features:

• Ruthenium center electrode: a 0.6 mm ruthenium alloy tip designed for ignitability and durability at high temperatures
• PSPE ground electrode: the projected square platinum electrode (PSPE) shape supports ignitability and service life in high-heat engines
• Solid copper core: 98% pure copper core for heat dissipation, conductivity and a wide heat range
• Trivalent metal plating: resists corrosion and seizing, so the plug installs and removes more easily
• Resistor design: helps suppress radio-frequency interference
