The Multiquip 409000 Glow Plug is a genuine OEM component designed for Multiquip pavement saw models SP605716, SP605726, SP605730, SP605736, and SP605720. Sourced directly from Multiquip, this glow plug meets the exact electrical and thermal specifications required for dependable cold-start performance in diesel-powered pavement saws. As a genuine OEM part, it delivers the correct heat range and resistance spec to match the engine's factory ignition system — no guesswork, no compromises. Confirm your model against the fitment list above before ordering to ensure a direct match.
Key Features
- Correct Heat Range for Diesel Cold Starts — Engineered to the precise thermal output the engine requires, ensuring the air-fuel mixture reaches ignition temperature even in cold conditions.
- Genuine OEM Electrical Spec — Matches the factory resistance and voltage draw spec, preventing stress on the glow plug controller or pre-heat relay.
- Direct Fitment for MQ Pavement Saws — Compatible with SP605716, SP605726, SP605730, SP605736, and SP605720 models; installs in the existing plug port without modification.
- Protects Engine Starting System — A correctly functioning glow plug reduces crank time and protects starter motor components from extended engagement cycles.
- Fuel System Safety Compliance — Proper glow plug function prevents incomplete combustion during start-up, reducing the risk of raw fuel buildup in the combustion chamber.
A glow plug is a resistive heating element threaded into each cylinder of a diesel engine. Before and during start-up, it heats the combustion chamber to the temperature needed to ignite diesel fuel — a critical function since diesel engines rely on heat of compression rather than a spark. When a glow plug fails or degrades, the engine becomes difficult or impossible to start in cool conditions, and even in warmer weather, misfires and excessive white smoke at start-up are common symptoms. Replacing a worn glow plug with the correct OEM unit restores proper cold-start behavior and protects the engine from the strain of repeated failed start attempts.
