Bosch 11032 Oxygen Sensor - Upstream

Bosch Actual OE Oxygen Sensor 11032

Bosch 11032 is a narrow-band, non-heated oxygen sensor built for specific-fit applications that require accurate air-fuel ratio feedback to the ECU. It supports stable combustion control and emissions management on classic BMW and Volvo applications, including BMW 528e, BMW 320i, and Volvo 760 upstream locations.

Key Features

• Actual OE Oxygen Sensor from Bosch Actual OE Oxygen Sensor line
• Narrow-band, non-heated sensor type for specific-fit applications
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Female connector with round connector shape and pin terminal type
• Wiring harness included; harness length measures 33.1 in
• Metal housing with steel finish for underbody durability
• Overall length measures 36.8 in; sealing surface to connector end measures 35.6 in

Detailed Description

Bosch 11032 is part of Bosch’s Actual OE Oxygen Sensor line, which draws on decades of original equipment development in oxygen sensing technology. Bosch uses narrow-band switching sensor design, ceramic sensing elements, and high-temperature-resistant materials to deliver precise lambda feedback for closed-loop fuel control. This Bosch oxygen sensor is a direct-fit replacement for select BMW and Saab applications, including BMW 528e upstream, BMW 320i upstream, and Saab 900 upstream.

This part cross-references 162858 and 1274367 for the same application. For buyers searching Bosch 11032 oxygen sensor replacement, Bosch 11032 BMW 528e upstream oxygen sensor, or Bosch 11032 Saab 900 upstream sensor, this part matches the listed OE-style fitment and connector configuration.

What It Is Used For

• Replacing a failed upstream oxygen sensor on compatible BMW and Saab vehicles
• Restoring accurate exhaust oxygen feedback to the ECU
• Addressing rich or lean fuel-control faults tied to sensor aging
• Correcting emissions-test failures caused by slow or inaccurate sensor response
• Resolving drivability issues linked to unstable closed-loop operation

Installation Notes and Tips

Verify the connector shape, terminal count, thread size, and harness length before installation. This Bosch 11032 sensor uses a threaded mount with an 18 mm thread diameter, so the exhaust bung must match the sensor specification. Confirm the upstream location and vehicle-specific application before replacement, especially on BMW 318i, BMW 533i, Volvo DL, and Volvo 760 listings.

For fitment-focused searches, this part fits 1982-1987 BMW 528e, upstream; 1979-1983 BMW 320i, upstream; 1979-1981 BMW 528i, upstream; 1983-1984 BMW 533i, upstream; 1984 BMW 318i, upstream; 1985 BMW 318i, upstream; 1983-1984 Volvo 760, upstream; 1984 Volvo DL, upstream; and 1986-1987 Saab 900, upstream.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development behind this design. The Actual OE Oxygen Sensor line is built to OE-proven standards for accurate signal output, stable heater-free operation, and durable performance in demanding exhaust environments.
