Product Details

The Bosch Diesel Glow Plug 0250603010 is built around Bosch DuraSpeed technology, which helps the glow plug reach operating temperature quickly and retain heat longer during diesel starting. That matters in Ford F-250 Super Duty and Ford F-350 Super Duty diesel engines where reliable cold starts, smooth combustion, and consistent engine management communication are important. Bosch also calibrates the glow plug for controlled post-glow operation, helping support quieter running and cleaner exhaust during warm-up.

This part cross-references Bosch Diesel Glow Plug 0250603010 for the same application.

What It Helps Address

• Hard starting in cold weather
• Extended cranking before the engine fires
• Rough idle immediately after startup
• Excess white smoke during diesel warm-up
• Glow plug fault conditions tied to slow heat-up or poor retention

Installation Notes and Tips

Verify engine code and build date before ordering, especially for 2012 Ford F-250 Super Duty and Ford F-350 Super Duty trucks built to 01/2012. Confirm the tapered seat, 8 mm thread diameter, 9 mm hex size, pin terminal, and 35 mm reach match the original glow plug specification. Clean the cylinder head threads and inspect the electrical connector before installation to help ensure proper seating and electrical contact.

Bosch supplies engine-management components with OE-level system integration in mind, and this glow plug is engineered to operate seamlessly within the diesel engine management system.
