OE 11781247406 — Oxygen Sensor for Bmw

Stock references leave Guangzhou within 7 working days. If 11781247406 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.

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 oxygen sensor the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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.

Match three things: the code on the part you are removing, the build-year range in the Applications table, and the mounting points visible in the reference photo. If all three line up, 11781247406 is a confirmed fit. Send your VIN and our export desk will double-check the ambiguous cases.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded oxygen sensor transfers stress to neighbouring components, so a small repair can grow into a full electrical & sensors rebuild. Book the replacement once the symptom is repeatable.
