BOSCH Duraterm High Speed Glow Plug 0250403018 [ GLP257 ]

Sheathed-element glow plugs guarantee comfortable starting, stable cold-running characteristics and emissions. Because they are wearing parts, their functional performance should be regularly checked by an expert. If the sheathed-element glow plug needs to be replaced, Bosch offers the right solution for every vehicle model – made from either metal or ceramic and with the appropriate heating element diameter.

Bosch sheathed-element glow plugs score high with their optimal property profile, which perfectly combines an operating voltage, maximum preheating temperature, heating time, and afterglow period to meet the requirements of every vehicle model. Additionally, they have a high resistance to chemical, mechanical, and thermal loads and a long service life.
