Main Description
This heated O2 sensor pair provides accurate, quick-response feedback to the engine control unit, enabling consistent idle, smoother acceleration, and better fuel economy. With magnetic induction sensing and a heating element, the sensors reach operating temperature faster, improving sensor reliability during cold starts and in real-world driving conditions. The kit covers upstream and downstream positions, ensuring comprehensive monitoring of the exhaust aftertreatment system for BMW F-series models listed in the compatibility notes. OEM-compatible parts 11788631047 and 11788631049 offer a precise fit and dependable replacement for worn or failed sensors.
Benefits & Tips
- Improved fuel efficiency and smoother engine performance by delivering accurate oxygen readings to the ECU in both the upstream and downstream positions.
- Faster catalyst warm-up and reduced emissions thanks to the built‑in heating element, which helps sensors reach operating temperature quickly after startup.
- Choose single or dual sensor configurations based on your vehicle’s needs: 11788631047 alone, 11788631049 alone, or both sensors installed together for full coverage.
