Oxygen Sensor for 2006-2008 BMW Z4 & More - Bosch 13951

Bosch 13951 oxygen sensor for the 2006-2008 BMW Z4 6-cylinder 3.2L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch O2 sensor is a heated, switching-type narrow-band design for the downstream position.

• Precise air-fuel-ratio feedback to the ECU for stable combustion control and lower emissions
• Metal housing, integrated heater element and TSP coating to resist vibration, corrosion and contamination
• Withstands exhaust streams up to 1,880°F
• Reaches operating temperature in under 10 seconds for quick closed-loop control

Quick facts

• Part: Bosch 13951 oxygen sensor
• Fits: 2006-2008 BMW Z4 6-cylinder 3.2L and other vehicles
• Position: Downstream
• Material: Metal
• Condition: New

A worn oxygen sensor can show up as a check engine light, poorer fuel economy or a rough idle. These signs alone do not prove the sensor is at fault, since an exhaust leak can cause similar readings. If this sensor is the cause, the replacement helps bring accurate air-fuel-ratio feedback back to the ECU.
