The Honda 98076-54720 Spark Plug (W14F-U) is a genuine OEM ignition component designed for a wide range of Honda generators, welder generators, horizontal shaft engines, and snow blowers, including the EB3000, EB4000, EM3000, EM4000, EMS4000, EMS4500, EW170, G150, G200, G300, G400, and HS50. Sourced directly from Honda, this spark plug carries the W14F-U designation — the variant qualifier buyers need to confirm before ordering, as multiple plug grades are listed across Honda's catalogue. Verify your engine's serial number against the fitment table to confirm this is the correct plug for your specific unit.
Key Features
- OEM Ignition Grade — the W14F-U heat range and electrode specification are set by Honda to deliver consistent spark timing and combustion efficiency across every application this plug is listed for
- Variant-Specific Designation — the W14F-U suffix identifies this plug's exact heat range; cross-check this against your engine's spec label before installing to ensure you have the right plug for your unit
- Broad Honda Fitment — listed for Honda G-series horizontal shaft engines, EB and EM generators, the EW170 welder generator, and the HS50 two-stage snow blower, covering an extensive range of Honda equipment
- Serial Number Verification Advised — Honda supersedes ignition parts at production breaks; confirm your machine's serial number against the compatibility table to ensure this is the current correct plug
- Reliable Cold Start and Running Performance — a fresh spark plug with the correct heat range prevents hard starting, misfires, and fuel fouling that a worn or incorrectly rated plug can cause
A spark plug ignites the compressed air-fuel mixture inside the combustion chamber, providing the timed spark that drives the power stroke of a four-stroke engine. The heat range of the plug — encoded in the W14F-U designation — determines how quickly the electrode dissipates heat; a plug that runs too hot can cause pre-ignition, while one that runs too cold will foul with carbon and misfire. Replacing a worn or fouled spark plug with the correct OEM-specified part restores clean ignition, improves throttle response, and helps the engine meet its rated output across generators, welder generators, G-series engines, and two-stage snow blowers.
