Bosch 17039 oxygen sensor for the 2008-2013 BMW M3 V8 4.0L and other vehicles reads the air-fuel ratio for the ECU. This upstream wideband A/F sensor reports the ratio continuously across the full lambda range, which gives the ECU more detailed information than a traditional switching sensor.
- Reaches operating temperature in less than 7 seconds for quick closed-loop control
- Withstands exhaust streams up to 1,880°F
- Integrated heater element and TSP coating resist vibration, corrosion and contamination
- Optimized heater control and ceramic construction cope with rapid load changes and harsh thermal cycles

A sensor that is wearing out can show up as a check engine light, rough running or poorer fuel economy, although other faults cause the same signs. With the engine off and cool, look over the wiring harness and connector for cracked insulation or damage; if the sensor is the cause, this one replaces it.
Fits
This Bosch O2 sensor is listed for a wide range of BMW models, including the 2008-2013 BMW M3 V8 4.0L, the 2006 BMW 323i 6-cylinder 2.5L and the 2006 BMW 325i 6-cylinder 3.0L.
