The Wacker Neuson Glow Plug is a genuine OEM glow plug designed for the LTN4Y and LTN5Y series light towers, including regional and voltage variants such as the LTN4Y 60 Hz, LTN4Y 120V/60Hz, LTN4Y SA, LTN4Y RH, LTN5Y, LTN5Y SA, LTN5Y CH, LTN5Y UK, LTN5Yp, LTN5Yp HD, LTN5Ypk, and LTN5Ypa. Sourced directly from Wacker Neuson, this is a genuine OEM component built to the same specification as the part that left the factory — ensuring correct fit and reliable cold-start performance across the full range of compatible units. Confirm your model against the fitment list before ordering to make sure is the right glow plug for your machine.
Key Features
- Genuine OEM Heat Output Spec — Meets the exact resistance and heating profile required by the diesel engine in LTN4Y and LTN5Y light towers, so the engine reaches ignition temperature correctly every time.
- Thread-and-Connector Match — Engineered to the correct thread pitch and terminal type for a direct drop-in installation with no adapting or reworking of existing wiring or ports.
- Broad LTN Series Coverage — Fits fourteen model variants across the LTN4Y and LTN5Y families, including SA, CH, UK, RH, HD, 60 Hz, 120V/60Hz, pk, pa, and p configurations.
- Cold-Start Reliability — A functioning glow plug brings the combustion chamber to the correct pre-heat temperature before cranking; a worn or failed plug causes hard starts, misfires, and excessive white smoke on startup.
- Electrical Safety Compliance — As a genuine OEM part, this glow plug meets the electrical and thermal specifications required by the engine management system, preventing overheating or misfire caused by out-of-spec aftermarket substitutes.
A glow plug is a small electric heating element threaded into each cylinder of a diesel engine. Before the engine cranks, the glow plugs heat the combustion chamber to a temperature high enough for diesel fuel to ignite without a spark — a process that is especially critical in cold weather or after extended downtime. When a glow plug fails or degrades, the engine struggles to start, runs rough at low temperatures, and may produce white or grey exhaust smoke until the cylinders come up to operating temperature. Replacing a worn glow plug restores clean, dependable starts and protects the engine from the strain of repeated failed cranking attempts.
