The Honda 98052-54740 Spark Plug (CR40/C50) is a genuine OEM replacement designed for the E40 generator. As a factory-original component, this spark plug is supplied to Honda's own specifications, ensuring the correct heat range, electrode gap, and thread dimensions for the E40. Sourcing the correct spark plug by part number 98052-54740 is the straightforward way to keep the ignition system performing as intended.
Key Features
- Correct Heat Range for the Application — the CR40/C50 designation identifies the specific plug grade Honda engineers specified for the E40 generator; using the correct grade prevents pre-ignition and fouling
- Genuine OEM Part — sourced directly from Honda, this spark plug meets the same specification as the plug installed at the factory, with no guesswork on cross-referencing
- Direct Replacement — this plug is listed for the E40 generator; verify your unit's serial number against the fitment table to confirm the correct application before ordering
- Ignition Performance — a worn or fouled spark plug causes hard starting, rough running, and poor fuel efficiency; replacing it with this part restores clean, consistent ignition
A spark plug is the component that ignites the air-fuel mixture inside the engine's combustion chamber. An electrical spark jumps the electrode gap at precisely the right moment in the engine's cycle, triggering combustion and driving the piston. Over time, the electrode wears, deposits build up on the tip, and the gap widens — all of which degrade spark quality. In a generator, a weak or intermittent spark shows up as difficulty starting, uneven power output, or the engine cutting out under load. Replacing a worn plug with the correct OEM unit restores dependable ignition and consistent output from the generator.
