The Multiquip 496018S Champion Spark Plug is a genuine OEM ignition component designed for Whiteman power buggy and Essick mixer series equipment, including WBH21EPA, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, WBH-21EF, and PRO20 models. As a factory-specified Champion plug, it delivers the exact heat range, thread pitch, and electrode configuration required by these engines — no guesswork on compatibility. Sourced directly from Multiquip's authorized parts supply, this is the same plug spec'd on the original assembly line. DHS Equipment stocks genuine Multiquip OEM parts so you can get your machine back in service with confidence.
Key Features
- Factory-Specified Heat Range: — Champion plug designation matches the engine's combustion requirements exactly, preventing fouling or pre-ignition caused by an incorrect heat range.
- Drop-In Thread and Reach Match: — Correct thread size, seat type, and plug reach for direct installation into the cylinder head — no rethreading or adapter needed.
- Genuine OEM Component: — Supplied as an authorized Multiquip OEM part, ensuring the electrode gap, shell torque spec, and insulator material meet the engine builder's original requirements.
- Broad Fitment Across Whiteman and Essick Lines: — Confirmed fit for WBH21EPA, WBH-16EAWD, WBH-16EAWDF, WBH-21EFP, WBH-21EF power buggies and the PRO20 Essick mixer.
- Ignition Reliability Under Load: — A fresh, correctly specified spark plug maintains consistent ignition timing and combustion efficiency — a worn or wrong-heat-range plug causes hard starts, rough idle, and power loss under working load.
A spark plug is the ignition point of every small gasoline engine — it fires a high-voltage spark at precisely the right moment to ignite the air-fuel mixture in the cylinder, driving the piston and producing power. The Champion designation on the 496018S reflects a specific heat range engineered to keep the electrode tip hot enough to burn off deposits but cool enough to avoid pre-ignition under the engine's normal operating load. When a spark plug wears out, gaps widen, electrodes erode, and the spark weakens — leading to misfires, poor throttle response, increased fuel consumption, and eventually a no-start condition. Replacing it on schedule with the correct OEM-spec plug keeps the engine firing cleanly and efficiently through every job.
