The Multiquip 2513212S Spark Plug is a genuine OEM component designed for HTN27K and HTN28K Whiteman ride-on power trowels. This is the correct factory-specified spark plug for the Kohler gasoline engine fitted to these mechanical trowel models, ensuring the ignition system performs exactly as engineered. Sourced directly through Multiquip's OEM supply chain, part number 2513212S is a direct replacement that installs without guesswork or fitment concerns. Keep your finishing equipment running at peak efficiency with the right part the first time.
Key Features
- OEM-Specified Ignition Match — Correct heat range, thread pitch, and electrode gap for the Kohler engine on these trowel models, delivering consistent spark and clean combustion.
- Drop-In Engine Replacement — Designed to thread directly into the cylinder head of HTN27K and HTN28K engines with no modifications to plug wires, boots, or ignition components.
- Confirmed Fitment — Verified for HTN27K and HTN28K Whiteman ride-on mechanical trowels; reference part number 2513212S when ordering to confirm compatibility.
- Consistent Power and Smooth Idle — A correctly gapped, properly specified spark plug maintains steady RPM under load, which is critical when blade pitch and finishing speed demand uninterrupted engine output.
- Fuel System Safety — A worn or fouled plug that misfires can cause unburned fuel to enter the exhaust; replacing on schedule with the correct OEM plug reduces that risk and keeps emissions in check.
A spark plug ignites the air-fuel mixture inside the engine cylinder, generating the combustion stroke that powers the machine. On a ride-on power trowel, where engine speed directly influences blade rotation and finishing quality, a healthy spark plug is essential for steady, responsive performance. When a plug wears, fouls, or loses its correct gap, the engine may misfire, idle roughly, lose power under load, or become difficult to start — all of which interrupt finishing work at a critical stage.
