Sheathed-element glow plugs guarantee comfortable starting, stable cold-running characteristics and low 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.
The 11 V metal sheathed-element glow plug Duraterm is an ongoing success with regard to reliability and service life. The patented, integrated control filament accelerates the warmup phase:
The metal sheathed-element glow plug Duraterm High Speed has been developed for low-voltage applications and works at a nominal voltage of either 4.4 or 5 V. Its particular strengths include high preheating and afterglow temperatures:
First-class technology that is the first choice for vehicle manufacturers: The ceramic sheathed-element glow plug DuraSpeed achieves a top performance of up to 1,300°C within less than two seconds, even in the case of extreme temperature values and has a nominal voltage of either 7 or 11 V.
