NGK 92650 Standard Spark Plug - LKR6E, Copper Core, Nickel Tip

The NGK 92650 is a Standard series spark plug built on NGK's proven copper-core design, identified under NGK's own designation as the LKR6E. It uses a solid copper core for strong heat dissipation and reliable electrical conductivity across a broad heat range, paired with a nickel center electrode and a nickel ground electrode in a surface discharge configuration. The plug's corrosion-resistant plating makes installation and removal easier and helps guard against thread seizure over time. NGK's patented triple gasket sealing process is designed to prevent combustion gas leakage at the seat, supporting a consistent seal through repeated heat cycles.

This is a Standard-line plug rather than a precious-metal (iridium/platinum) plug, making it a straightforward, cost-effective replacement option for engines specified to use this design. It ships as a single spark plug. Always check your engine's maintenance manual and use only the spark plug recommended by your engine's original equipment manufacturer, since the wrong plug can reduce performance and fuel economy or cause engine damage.
