NGK Spark Plug Stock # 2460

The NGK Spark Plug Stock # 2460 (BKR5ES) is the go-to ignition component for mechanics and engine builders who demand reliable cold-start performance and consistent combustion across the RPM band. This spark plug is engineered for a wide range of automotive applications, from daily drivers to modified engines running optimized fuel maps. Whether you're tuning a carbureted classic or maintaining a late-model four-cylinder, the BKR5ES delivers the thermal stability and electrode durability that keeps your engine firing cleanly under varied load conditions.

NGK's proven copper-core design in the BKR5ES allows superior heat transfer away from the electrode, preventing fouling and pre-ignition in high-output engines while maintaining excellent low-temperature performance for cold starts. The tapered seat design ensures a gas-tight seal in standard 14mm spark plug holes, eliminating gap creep and misfires caused by vibration or thermal cycling. NGK's quality-control standards mean you get consistent electrode geometry and gap tolerances—critical factors when you're diagnosing or rebuilding carburetors and ignition systems where spark timing precision matters.

Mechanics and enthusiasts rely on the BKR5ES for both stock restorations and mild to moderate engine modifications, including cam swaps, intake upgrades, and carburetor tuning where factory spark plugs fall short. Installation is straightforward—simply gap to your engine's specification (typically 0.028–0.032 inches for most applications), apply a light coat of anti-seize to the threads, and torque to manufacturer specs. Buy the NGK Spark Plug Stock # 2460 when you need proven OEM-grade ignition reliability that won't leave you troubleshooting lean-burn issues or carbon buildup in the cylinder head.
