The Honda 98079-56145 Spark Plug (BPR6ES-11) is a genuine OEM ignition component designed for GX340 horizontal shaft engines, EB5000, EG5000, and EM5000 generators, EW171 welder generators, and H5013 and RT5000 multi-purpose tractors. As a factory-original part, this spark plug is specified by Honda to deliver consistent ignition performance across every application it is listed for. Always verify your unit's serial number against the fitment table to confirm this is the correct plug for your build. Sourcing from DHS Equipment means you are getting an authentic Honda part, not a generic substitute.
Key Features
- OEM Ignition Specification — the BPR6ES-11 heat range and electrode gap are specified by Honda for the engines and equipment this plug covers, ensuring the spark event happens at the right intensity and timing every time
- Direct Drop-In Replacement — this plug threads in and connects to the ignition lead exactly as the original, with no alteration to the ignition system required
- Broad Honda Fitment — listed for GX340 engines, EB5000, EG5000, and EM5000 generators, the EW171 welder generator, and H5013 and RT5000 multi-purpose tractors; confirm your serial number against the fitment table before ordering
- Consistent Cold-Start and Running Performance — a correctly specified plug fires cleanly at startup and sustains a stable flame kernel under load; a worn or fouled plug causes hard starting, misfires, and increased fuel consumption
A spark plug is the component that ignites the compressed air-fuel mixture inside the combustion chamber. At precisely the right moment in the engine's cycle, the ignition coil sends a high-voltage pulse across the plug's electrode gap, creating the spark that drives the piston down and puts power to the crankshaft. When a spark plug degrades — through electrode wear, carbon fouling, or a gap that has grown beyond specification — ignition becomes inconsistent, leading to hard starting, rough running, loss of power, and higher fuel use. Replacing a worn plug with the correct Honda OEM unit restores clean, reliable combustion and brings the engine back to the performance it was designed to deliver.
