Key Features
- OEM-Spec Heating Element: — Matched to the correct resistance and heat output required by the diesel engine, ensuring proper pre-chamber temperature for combustion.
- Direct Drop-In Replacement: — Threads directly into the original glow plug port with no modifications to wiring harness or engine block.
- Broad Fitment Coverage: — Compatible with DAW500SA4, DLW300ES, DLW330X2, DLW400ESA4, DAC7000SS series, DAC7000SSA, DAC7000SSW, and MRH601DS equipment.
- Cold-Start Reliability: — A functioning glow plug brings combustion chamber air to ignition temperature before cranking, critical in low-temperature conditions. A failed plug leads to hard starts, excessive cranking, and incomplete combustion.
- Fuel System Safety Compliance: — Correct glow plug operation prevents unburned fuel from accumulating in the combustion chamber, reducing the risk of rough starts and engine damage over time.
- Genuine Multiquip OEM Part: — Carries the full backing of Multiquip's parts program, ensuring this is the same component used in original equipment assembly.
A glow plug is an electric heating element threaded into each cylinder of a diesel engine. Because diesel engines rely on compression heat rather than a spark to ignite fuel, glow plugs preheat the combustion chamber air during cold starts to reach the temperature needed for reliable ignition. When a glow plug fails or degrades, the engine may crank without firing, produce white smoke at startup, or run rough until it reaches full operating temperature. Replacing a worn glow plug with the correct OEM specification part restores normal start behavior and protects the engine from the stress of prolonged cranking.
