Bosch 13475 oxygen sensor for the 2000-2003 BMW Z8 V8 5.0L, the 2003 Z8 V8 4.8L and other vehicles reads the oxygen in the exhaust and sends air-fuel-ratio measurements to the ECU. It helps the ECU keep combustion stable and helps reduce emissions.
- Switching-Type narrow-band design with an integrated heater element
- Ceramic elements and optimized heater control for consistent readings under thermal and vibration loads
- Withstands exhaust gas up to 1,880°F; metal housing and TSP coating resist vibration, corrosion and contamination
- Reaches operating temperature in less than 10 seconds for quick closed-loop control and cold-start response
