With a long history of diesel fuel injection expertise and innovation, Bosch leads the way in glow plug technology with its patented Duraterm dualcontrol 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:All Glow Plugs are 100% tested before they leave the factory to ensure highest quality standardsWith our patented and revolutionary Duraterm Technology, the glow plug reaches higher temperatures more quickly for fast engine start-up even at -18 FGlow tube material withstands extreme operating temperatures and is corrosion and vibration resistant for long service lifeTwin Viton seals promote longer life by protecting the coils against damage caused by exhaust gasesConnectors designed to OE specifications for precise fit and easy installation
