Description

Bosch 17037 oxygen sensor for the 2006 BMW 323i 6-cylinder 2.5L and other vehicles measures the air-fuel ratio in the exhaust and reports it to the ECU. This oxygen sensor is a wide-band type for the upstream position.

Wideband A/F sensing gives the ECU continuous air-fuel ratio readings across the full lambda range
Ceramic construction and optimized heater control for reliable performance through rapid load changes and harsh thermal cycles
Withstands exhaust streams up to 1,880°F; metal housing, integrated heater and TSP coating resist vibration, corrosion and contamination
Reaches operating temperature in under 7 seconds for quick closed-loop control and improved cold-start performance

Quick facts

Part: Bosch 17037 oxygen sensor
Fits: 2006 BMW 323i 6-cylinder 2.5L and other vehicles
Position: Upstream
Material: Metal housing
Condition: New

A lit check engine light, higher fuel use or a rough idle can mean the sensor is wearing out. Those signs alone do not prove it, since a vacuum leak can throw off the readings in the same way. If the sensor is the cause, this one replaces it.

Fits

The 2006 BMW 323i 6-cylinder 2.5L, the 2006 BMW 325i 6-cylinder 3.0L and the 2006 BMW 325xi 6-cylinder 3.0L are among the BMW models this sensor fits. If your BMW is not named here, look up its year and engine on the Buyer's Guide tab. This listing is one sensor, and the fitment lists one for the upstream position.
