The Honda 98079-5587C Spark Plug (BKR5E-E) is a genuine OEM replacement designed for GX440 horizontal shaft engines. As a factory-sourced component, this spark plug carries the exact heat range, electrode gap, and thread specification Honda engineers selected for this engine — no guesswork required. Buyers should verify their serial number against the fitment table to confirm part number 98079-5587C is correct for their specific production run.
Key Features
- OEM Heat Range and Electrode Specification — the BKR5E-E designation encodes the precise heat range and electrode configuration Honda specifies for the GX440, ensuring complete combustion and consistent ignition performance
- Direct OEM Replacement — sourced directly from Honda, this plug installs to OEM torque spec without modification, restoring the ignition system to its original condition
- GX440 Fitment — listed for GX440 horizontal shaft engines; confirm your serial number against the fitment table before ordering, as Honda supersedes spark plug part numbers at production breaks
- Ignition Reliability — a worn or fouled spark plug causes hard starting, rough running, and increased fuel consumption; replacing it with the correct OEM plug restores clean, reliable ignition
A spark plug is the component responsible for igniting the air-fuel mixture inside the engine's combustion chamber. Each firing cycle, it delivers a high-voltage electrical spark across its electrode gap at precisely the right moment, triggering combustion that drives the piston and produces power. When a spark plug wears out, its electrode gap widens, the insulator fouls, or the heat range drifts — leading to misfires, difficult starting, and sluggish performance across the equipment the GX440 powers.
