NGK 94705 LKR7BHX Ruthenium HX High Ignitability Spark Plug

The NGK 94705 Ruthenium HX spark plug (NGK plug number LKR7BHX) is a high-ignitability replacement spark plug built on NGK's OE technology. It has a fine-wire ruthenium center electrode and a projected square platinum ground electrode (PSPE). This design gives a more complete fuel burn, which supports quick throttle response, smooth idle and reliable cold starts.

Key Features:

• Fine-wire ruthenium center electrode (0.6 mm) for ignitability and durability at high temperatures
• Projected square platinum ground electrode (PSPE) with a cut-back design for high ignitability and long service life
• Copper-cored center and ground electrodes for heat dissipation and conductivity
• Built-in 5,000 ohm resistor to help suppress electromagnetic interference
• Ceramic insulator with a non-removable terminal nut
