BMW Mini Series Oxygen Sensor 11787848482 0258027088, Durable OEM-grade replacement

When your BMW Mini experiences idle instability, noticeably higher fuel consumption, weak acceleration, or the engine check light on, it usually indicates aging or failed oxygen sensors. When functioning properly, the sensor provides real-time feedback of the air-fuel ratio to the ECU to ensure optimal combustion efficiency, emissions, and performance. This is an OEM-equivalent replacement, OEM numbers 11787848482 / 0258027088 / 2345165; fits BMW Mini series (e.g., R50/R52/R53 1.6L engines). Installation must be done with the engine cold; use a specialized socket to avoid thread damage; apply anti-seize before installation; tighten to the specified torque; ensure wiring harness away from high-temperature exhaust areas.
