The Wacker Neuson Glow Plug is a genuine OEM component designed for the HI750GM, HI750GMHD, CUB700GM, and HI900DGM series indirect-fired diesel air heaters. As a direct factory replacement, the meets the original engineering specification for heat output and electrical resistance, ensuring dependable cold-weather ignition performance. This glow plug is confirmed compatible across multiple HI-series configurations, including surge brake and mobile genset variants. Keep a verified OEM part on hand to avoid heating interruptions on the jobsite during critical cold-weather operations.
Key Features
- Correct Electrical Resistance Spec — Genuine OEM construction ensures the glow plug meets the original resistance and heat output ratings required for consistent diesel ignition in Wacker Neuson HI-series heaters.
- Drop-In Replacement — Matches the original thread pitch, tip geometry, and connector type for a straightforward swap with no modifications to the heater's ignition circuit.
- Broad HI-Series Compatibility — Fits HI750GM, HI750GMHD, CUB700GM, and HI900DGM indirect-fired air heaters, covering standard, surge brake, mobile genset, and HD mobile configurations.
- Cold-Start Reliability — A properly functioning glow plug delivers the pre-heat energy diesel combustion requires at low ambient temperatures; a worn or failed plug causes hard starts, misfires, or complete no-heat faults.
- Fuel System Safety Compliance — Using a correctly rated OEM glow plug prevents over-temperature conditions in the combustion chamber that can result from mismatched aftermarket substitutes, supporting safe heater operation in enclosed or temporary-heat applications.
A glow plug is an electrically heated ignition element installed in the combustion chamber of a diesel-fueled heater. When the heater is switched on, the glow plug heats rapidly to raise the local air temperature high enough for diesel fuel to ignite reliably — a function that becomes especially critical at sub-zero ambient temperatures where compression heat alone is insufficient. If the glow plug degrades or fails, the heater will struggle to light, produce fault codes, or shut down entirely on ignition lockout, leaving a worksite without heat until the part is replaced.
