The Honda 98076-56724 Spark Plug (W20FS-U) is a genuine OEM spark plug designed for E300 generators, G150, G200, G300, and G400 horizontal shaft engines, and the HS50 two-stage snow blower. As a factory-sourced component, this spark plug is the exact specification Honda engineers selected for these machines — not a generic substitute. Verify the part number 98076-56724 against your machine's serial number and parts list before ordering, as Honda supersedes ignition components across production runs.
Key Features
- OEM Ignition Specification — the W20FS-U heat range and electrode gap are set to Honda's exact specification for these engines and generators, ensuring the correct spark energy at every RPM
- Drop-In Replacement — threads, reach, and terminal style match the original, so installation requires no modifications to the cylinder head or ignition wire
- Broad Genuine OEM Coverage — a single Honda OEM part covering E300 generators, G-series horizontal shaft engines (including G150, G200, G300, and G400), and the HS50 two-stage snow blower
- Check Your Serial Number — Honda updates ignition specifications at production breaks; confirm your machine's serial number against the fitment table to be sure this is the correct plug for your unit
- Clean Combustion — a properly gapped, correctly specified spark plug promotes complete fuel burn, smooth starting, and stable idle; a worn or fouled plug causes hard starts, misfires, and increased fuel consumption
A spark plug is the ignition source in a four-stroke engine: a high-voltage pulse from the ignition coil jumps the electrode gap and ignites the compressed air-fuel mixture in the combustion chamber. The heat range of the plug — encoded in the W20FS-U designation — determines how quickly the tip sheds heat, keeping it hot enough to burn off deposits without overheating and causing pre-ignition. When a spark plug wears, its gap widens, its electrode erodes, or its ceramic insulator cracks, any of which can produce a weak or absent spark. The result is hard starting, rough running, and wasted fuel until the plug is replaced.
