The Multiquip 8973641280 Glow Plug DCA25USI 4LE2 is a genuine OEM replacement designed for the DCA25USI ultra-silent diesel generator. Sourced directly from Multiquip, this part carries the correct specifications for the Isuzu 4LE2 engine fitted in DCA25USI units, ensuring it seats and performs exactly as the original. When a glow plug fails or weakens, cold-start reliability suffers and the engine may crank without firing — replacing it with the correct OEM part restores dependable ignition every time. DHS Equipment supplies this part as a stocked OEM component ready for professional service applications.
Key Features
- OEM-Grade Heating Element — Manufactured to the exact resistance and heat-up profile specified for the Isuzu 4LE2 engine, delivering consistent pre-chamber temperatures for proper combustion ignition.
- Direct Engine Fit for 4LE2 — Threaded to the correct pitch and torque specification for the 4LE2 cylinder head, dropping straight in without modification to the engine block or wiring harness.
- DCA25USI Generator Compatibility — Confirmed fitment for the Multiquip DCA25USI ultra-silent diesel generator series, so you can order with confidence for that specific unit.
- Cold-Start Performance Restored — A fully functional glow plug brings the combustion chamber to operating temperature before cranking, preventing hard starts, white smoke, and misfires in cold or damp conditions.
- Fuel System Safety Compliance — Using the OEM-specified glow plug prevents incomplete combustion events that can deposit unburned fuel in the exhaust system, protecting downstream components and operator safety.
A glow plug is a pencil-shaped heating element threaded into each cylinder of a diesel engine. Before the starter engages, the glow plugs heat the pre-combustion chamber to a temperature high enough for diesel fuel to ignite reliably — especially critical in cold ambient conditions where compression alone may not be sufficient. When a glow plug wears out or fails entirely, the result is hard starting, excessive white smoke at startup, rough idling, and increased wear on the starter motor. Replacing a failed plug promptly with the correct OEM part — like the Multiquip 8973641280 — keeps the 4LE2 engine starting cleanly and running efficiently from the first crank.
