The Honda 98079-5787C Spark Plug (BKR7E-E) is a genuine OEM spark plug designed for the GX440 horizontal shaft engine. As a factory-sourced component, this plug matches the exact heat range and electrode specification Honda engineers selected for the GX440 — not a generic substitute. Confirm part number 98079-5787C against your engine's serial number in the fitment table to ensure this is the correct plug for your serial range before ordering.
Key Features
- OEM Heat Range and Electrode Specification — the BKR7E-E designation identifies a specific heat range and electrode design; using the correct plug prevents pre-ignition, fouling, and misfires that a mismatched substitute can cause.
- Direct OEM Replacement — supplied by Honda as the factory replacement for GX440 horizontal shaft engines, this plug installs to the same thread pitch and reach as the original.
- Serial-Range Verification — Honda supersedes parts at production breaks, so cross-check your engine serial number against the fitment table to confirm part number 98079-5787C is correct for your unit.
A spark plug ignites the compressed air-fuel mixture inside the engine's combustion chamber, firing once per power stroke to keep the engine running. The heat range of the plug — encoded in the BKR7E-E designation — determines how efficiently the electrode dissipates combustion heat: too cold a range causes carbon fouling; too hot a range risks pre-ignition and electrode damage. A worn or degraded plug produces a weak or inconsistent spark, leading to hard starting, rough running, elevated fuel consumption, and loss of power in the GX440 engine.
