OE 11781742050 — Oxygen Sensor for Bmw

Wholesale pricing for 11781742050 depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 11781742050 to confirm the right replacement.

Position depends on the platform. On most Bmw applications the oxygen sensor sits on the electrical & sensors assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

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.
