Installation Notes and Tips

Verify thread diameter, reach, seat type, and terminal style before installation. Clean the cylinder head threads carefully and inspect the electrical connection for corrosion or looseness before fitting the new glow plug. Use the vehicle service procedure for torque and electrical testing to protect the glow plug and cylinder head.

Quality Assurance

Bosch is a long-established diesel fuel and ignition technology brand, and this glow plug reflects that engineering background with a controlled-heating design for diesel starting performance. Confirm fitment by year, make, model, and engine service information before ordering.
