Product Details

Bosch 0250202023 is a diesel glow plug engineered around Bosch’s Duraterm line, which uses a dual heating and regulating coil system to manage current flow efficiently. That design helps the plug reach higher temperatures faster, reducing glow wait time and supporting smoother cold starts. In vehicles with post-glow control, the same technology supports a more efficient warm-up phase after startup. This part number 0250202023 is a practical OE-style replacement for diesel service work where correct thread size, seat type, and terminal style matter.

This part cross-references OE numbers N10579201 and N10579202 for the same application.
