The Multiquip EM251 Spark Plug is a genuine OEM Spark Plug designed for a wide range of Multiquip and Whiteman equipment, including MQ Mixers (MC64SK, MC64PK, MC94SK, MC94PK), walk-behind rollers (V305EK), masonry and flat saws (MP115E, MP120E, MP1455HP, MP1H, MP2050E1, MP2050E3, MP2090HP, MP25E1, MP25E3, MP275E3, MP2H, MP3, SP118, SP1E16A, SP2S20H), and Whiteman ride-on and walk-behind power trowels (HTN27K, HTN28K, JTO-SERIES, B46S90). As a genuine OEM component sourced directly through Multiquip, the EM251 meets the exact ignition specifications required by each covered machine. Stocking this plug ensures you have the right part on hand when routine maintenance or an unexpected ignition issue calls for a fast swap.
Key Features
- Genuine OEM Ignition Spec: — Manufactured to the exact heat range, thread pitch, and electrode gap specified for each covered engine, ensuring complete combustion and consistent ignition timing.
- Broad Cross-Equipment Compatibility: — One part number covers concrete mixers, walk-behind rollers, masonry saws, flat saws, and ride-on and walk-behind power trowels across multiple Multiquip and Whiteman model families.
- Drop-In Fitment: — Threads directly into the cylinder head with no modification — correct reach and seat type for every listed application from MQ Mixers to HTN27K and HTN28K trowels.
- Protects Engine Performance: — A correctly gapped, heat-matched plug supports full power output and smooth idle; a worn or fouled plug leads to hard starting, misfires, and increased fuel consumption across all covered equipment.
- Fuel System Safety Compliance: — Using the manufacturer-specified plug prevents pre-ignition and detonation risks that can arise from an incorrect heat range — particularly important on saw and trowel engines operating under sustained load.
A spark plug ignites the air-fuel mixture inside the engine cylinder, providing the timed combustion event that drives the piston and powers the machine. The plug must deliver a reliable spark at the right moment and dissipate heat at a rate matched to the engine's design — too cold and deposits foul the electrode; too hot and pre-ignition damage follows. When a spark plug wears out or fails, symptoms range from rough running and hard starting to complete no-start conditions, making it one of the most critical routine service items on any gasoline-powered piece of equipment.
