Bosch 80014 Standard Diesel Glow Plug OEM Replacement

The Bosch 80014 (OEM #0250202005) is a standard sheathed-element diesel glow plug engineered to OE specifications for reliable cold starts and clean combustion in diesel engines. Bosch is the original equipment glow plug supplier for most European diesel applications, making this a direct, confidence-inspiring replacement for worn or failed plugs.

Diesel engines depend on preheated combustion chamber air rather than a spark to ignite fuel. The glow plug rapidly brings the prechamber or combustion chamber to the proper temperature, ensuring clean, complete fuel ignition — especially during cold starts. The high-grade glow tube construction is built to withstand sustained operating temperatures up to 1100°C while resisting corrosion for long service life.
