Bosch Duraterm Glow Plug with Self-Regulating Technology

Bosch Duraterm diesel glow plugs use patented self-regulating technology for fast, dependable cold starts. The dual-control regulating and heating coil directs current draw so the glow plug reaches operating temperature quickly. This cuts glow wait time by more than 50%. Bosch has long experience in diesel fuel injection and glow plug technology. Duraterm plugs are built to OE specifications as direct-fit replacement glow plugs for diesel cars and light trucks.

Key Features:

• Self-regulating dual-control coil: The regulating coil keeps the heating element in its optimal 1000-1100°C temperature range. This helps prevent damage from over-voltage or overheating.
• Faster start-up: The coil reaches higher temperatures more quickly, which helps in cold weather.
• Post-glow capability: In vehicles with a post-glow control system, the plug keeps heating for up to three minutes after the engine starts. This can improve engine performance and reduce smoke emissions and combustion noise.
• Durable materials: The glow tube is made of corrosion- and vibration-resistant Inconel 601. Fine-grained ceramic insulating powder gives good electrical insulation and thermal conductivity.
• Twin Viton seals: The seals protect the coils from exhaust gas damage and help the plug last longer.
• Anti-seize threads: Nickel-plated, rolled threads add strength and help prevent seizing.
• Easy installation: Connectors are OE or OE-spec for a precise fit.

Bosch recommends replacing all glow plugs in an engine at the same time. This reduces downtime and labor costs. Duraterm technology is available for most diesel car and light truck applications. Other applications use standard glow plug technology as the OE specifications call for.
