Product Details

Duraterm Diesel Glow Plug (80 034) by Bosch®. Bosch Glow Plugs are critical for starting up a diesel engine. The pre-heat, starting and post-glow phases of a glow plug’s operation affect not only the start-up function, but the vehicle’s overall performance as well. With a long history of diesel fuel injection expertise and innovation, Bosch engineers manufacture glow plugs to withstand the rigorous demands of today’s diesel engines.

  • Engineered for superior cold-start performance
  • Regulating coil controls current draw for rapid heat-up of the heating coil
  • Heating coil provides rapid heat-up of the glow tube and quick start-up
  • Glow tube material (Inconel 601) for exceptional vibration and corrosion resistance
  • Fine-grained ceramic insulating powder provides superior electrical insulation and high thermal conductivity
  • Twin Viton seals protect coils from exhaust gas damage for long service
  • OE-design connectors for a precise fit and ease of installation

Bosch provides the right glow plugs to give you dependable cold start-up performance season after season. They are designed to meet and/or exceed the OE glow plug specifications so you can replace your OE glow plugs with complete confidence. What makes Bosch glow plugs different from other glow plugs is their exclusive Duraterm technology: they utilize a self-regulating control system that reduces glow wait time by more than 50%. The patented dual-control heating and regulating coil effectively directs current draw, allowing the glow plug to reach higher temperatures more quickly for faster engine start-up. The regulating coil keeps the heating element within the 1000° – 1100°C optimal temperature range, preventing engine damage due to overvoltage or overheating. Thanks to the Inconel 601 glow tube material, Bosch glow plugs provide exceptional corrosion and vibration resistance for a longer service life.
