Bosch Duraterm Glow Plug Technology With a long history of diesel fuel injection expertise and innovation, Bosch leads the way in glow plug technology with its patented Duraterm dual-control coil design. This technology utilizes a self-regulating system that reduces glow wait time by more than 50%. The patented dual control regulating and heating coil system effectively directs current draw, enabling the glow plug to reach higher temperatures more quickly for faster engine start-up. For vehicles with a post-glow control system, this advanced technology results in a post-glow heating phase which allows for more efficient overall engine performance. Product Features:Glow plug reaches higher temperatures more quickly for fast engine start-upRegulating coil controls current draw for rapid heat-up of heating coilHeating coil provides rapid heat-up of the glow tube and quick start-upGlow tube material resists corrosion and vibration for long service lifeFine-grained ceramic insulating powder provides superior electrical insulation and high thermal conductivityTwin Viton seals protect coils from exhaust gas damage for long lifeConnectors designed to OE specifications precise fit and easy installation
