The Multiquip 9807354740 Spark Plug BM-4A is a genuine OEM ignition component designed for GX100-powered equipment. This OEM-sourced spark plug is built to the exact specification required by the GX100 engine, ensuring consistent spark delivery and dependable starts across Multiquip rammer models running the GX100 engine platform. Cross-reference HC- confirms direct application compatibility, making part verification straightforward before ordering.
Key Features
- OEM Ignition Specification — Manufactured to the exact heat range, electrode gap, and thread specification required by the GX100 engine — not a general-purpose substitute.
- Direct Drop-In Installation — Threads directly into the GX100 cylinder head with no modification, matching the original plug's reach and seat type for a clean install every time.
- GX100 Engine Fitment — Confirmed fit for Multiquip equipment powered by the GX100 engine, including MTX-series rammers equipped with the GX100 powerhead.
- Consistent Combustion Performance — A properly functioning spark plug delivers a clean, timed spark that supports full power output and smooth throttle response — a worn plug causes hard starting, misfires, and lost compaction force.
- Genuine OEM Sourcing — Supplied as a genuine Multiquip OEM part, cross-referenced as HC-0928168, so you receive the same plug spec the machine shipped with.
A spark plug is the ignition point of a small gasoline engine — it fires a precisely timed electrical spark that ignites the air-fuel mixture inside the cylinder to drive the piston and keep the engine running. On GX100-powered rammers, the spark plug works under high heat and mechanical stress with every stroke of the machine. When a spark plug wears out, the electrode gap widens, spark energy drops, and the engine becomes difficult to start, runs roughly, or loses power under load. Replacing it with the correct OEM-spec plug restores clean ignition and keeps the engine performing at its rated output.
