Key Features
- Genuine OEM Ignition Performance — sourced directly from Honda, this plug delivers the correct heat range and electrode geometry for consistent ignition in the G-series and E/EG-series equipment it serves
- Drop-In Replacement — replaces the original plug with no modifications, restoring correct thread reach and seat type for each listed engine and generator
- Broad Honda Compatibility — listed for the G150, G200, G30, G35, G42, G65, G80, GS65 horizontal shaft engines and the E1500, E2500, EG1500, and ES3500 generators; verify your serial number against the fitment table to confirm the correct plug for your unit
- Reliable Cold Starting and Clean Combustion — a properly gapped, correctly rated plug fires the air-fuel charge completely, supporting smooth starting and preventing fouling or misfires that cause rough running and increased fuel consumption
A spark plug ignites the compressed air-fuel mixture inside the combustion chamber, initiating the power stroke that drives the engine. The heat range designation — B6HS in this case — determines how quickly the plug transfers heat away from its tip; too cold a range causes fouling, while too hot a range risks pre-ignition. When a spark plug wears out or its electrode gap widens beyond spec, ignition becomes inconsistent, leading to hard starting, rough idling, misfires, and reduced output from the engine or generator. Replacing the plug with the correct OEM unit, part number 98076-56740, restores clean, reliable ignition from the first pull.
