Bosch 0250603008 DuraSpeed Diesel Glow Plug

The Bosch 0250603008 DuraSpeed diesel glow plug is a direct-fit replacement engineered for 3.0L EcoDiesel engines found in Ram 1500 and Jeep Grand Cherokee vehicles. This OE-quality glow plug features Bosch's patented Duraterm dual control coil technology that reduces glow wait time by more than 50%, delivering fast and reliable cold-weather starting even at temperatures as low as -18°F (-28°C).

Key Features:

• Patented Duraterm technology with dual control regulating and heating coil system for rapid heat-up and faster engine start-up
• Self-regulating ceramic element operates at optimal temperatures between 1000°-1100°C (1832°-2012°F), preventing engine damage from overvoltage or overheating
• Extended post-glow phase up to 15 minutes for reduced emissions, quieter cold-idle operation, and improved overall engine performance
• Inconel 601 glow tube material provides exceptional corrosion and vibration resistance for longer service life
• Twin Viton O-ring seals protect internal coils from exhaust gas damage
• Nickel-plated rolled threads increase strength and prevent seizure during installation and removal
• M8 x 1.0 thread size with conical seat for positive sealing to the combustion chamber
• OE-specification connectors designed for precise fit and easy installation

This glow plug supports diesel particulate filter regeneration and minimizes smoke during load changes. Each 3.0L EcoDiesel engine requires 6 glow plugs total. When one glow plug fails, it's recommended to replace all six to ensure consistent performance and minimize future labor costs.
