OE 0250201010 — Glow Plug for Mercedes-Benz

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a glow plug the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 0250201010 with other engine & fuel system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Every shipment of 0250201010 leaves with a packing list, photo documentation and a QC report. Warranty terms are agreed per contract and reference that inspection record; claims are settled in writing against the documentation.

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.
