The Multiquip EM26737 Spark Plug VH4D is a genuine OEM ignition component designed for VH4D series equipment. Sourced directly from Multiquip, this Champion 564 spark plug delivers the correct heat range, electrode gap, and thread specification required by the VH4D engine for consistent, dependable ignition. As a genuine OEM part, EM26737 ensures a direct match to the original component without guesswork on compatibility. If your VH4D is misfiring, hard to start, or running rough, swapping in the correct spark plug is one of the fastest ways to restore clean engine operation.
Key Features
- Correct Heat Range for the VH4D Engine — Matched to the thermal demands of the VH4D, this plug dissipates combustion heat at the rate the engine was engineered around, preventing pre-ignition and fouling.
- Champion 564 Specification — This is the OEM-specified Champion 564 plug, meaning electrode material, thread pitch, reach, and seat type are all exactly what the VH4D engine requires.
- Genuine Multiquip OEM Part — Authenticated OEM replacement that meets the same production standards as the plug installed at the factory — no substitutions or approximations.
- Direct Fitment for VH4D Equipment — Confirmed compatibility with VH4D series machines; installs directly into the existing plug port with the correct torque spec and seating geometry.
- Restores Clean Ignition Performance — A worn or fouled spark plug causes hard starts, rough idling, increased fuel consumption, and power loss — replacing with this part restores the sharp, consistent spark the engine depends on.
A spark plug is the ignition source for the engine's combustion cycle — it fires a high-voltage spark at precisely timed intervals to ignite the air-fuel mixture inside the cylinder. When the plug is worn, fouled with carbon deposits, or operating at the wrong heat range, ignition becomes inconsistent, leading to misfires, difficulty starting, and lost power output. Over time, a degraded spark plug puts additional strain on other ignition and fuel system components. Replacing the plug on a regular maintenance schedule — or at the first sign of rough running — keeps the engine firing cleanly and efficiently.
