The Honda 98076-54911 Spark Plug (BP-4HS-10) is a genuine OEM replacement designed for G150, G200, G300, and G400 horizontal shaft engines, HS50 two-stage snow blowers, and WB20 and WB30 water pumps. As a factory-original component, this spark plug is specified to deliver the correct heat range and electrode gap Honda engineers require for consistent ignition across these machines. Verify your unit's serial number against the fitment table to confirm part number 98076-54911 is the right match for your serial range before ordering.
Key Features
- OEM Heat Range and Electrode Specification — the BP-4HS-10 designation identifies the exact heat range, reach, and pre-set gap Honda specifies for these engines and equipment, ensuring the spark plug fires the air-fuel mixture at the right moment in the combustion cycle
- Direct OEM Replacement — sourced directly from Honda, this spark plug drops into any compatible unit without adjustment to the plug seat or thread pitch
- Broad Fitment Across Multiple Machine Classes — covers G-series horizontal shaft engines including the G150, G200, G300, and G400, as well as HS50 two-stage snow blowers and WB20 and WB30 water pumps
- Serial Number Verification Recommended — Honda supersedes parts at serial breaks; always cross-check your machine's serial number against the fitment table to confirm this is the correct plug for your unit
- Ignition Reliability — a spark plug at the correct heat range prevents fouling and pre-ignition; a worn or incorrect plug can cause hard starting, rough running, and elevated fuel consumption
A spark plug ignites the compressed air-fuel mixture inside the combustion chamber, and the precise heat range of the plug determines how well it burns off carbon deposits during normal operation. The BP-4HS-10 designation tells you the plug's reach, thread size, and thermal rating — all matched to the displacement and operating conditions of the engines and equipment it serves. When a spark plug degrades, symptoms range from difficult cold starts and misfires to poor throttle response and increased fuel use, making timely replacement one of the most straightforward ways to keep an engine running at its best.
