Bosch 17217 Oxygen Sensor - Upstream

Bosch Wideband O2 Sensor for Mini Cooper

Bosch 17217 is an Actual OE Oxygen Sensor built for precise air-fuel ratio monitoring in wideband applications. It delivers fast, continuous feedback to the ECU, helping maintain accurate mixture control on 2007-2010 Mini Cooper upstream positions.

Key Features

• Wideband A/F oxygen sensor for detailed lambda measurement across the full operating range
• Heated design with optimized heater control for quicker sensor activity
• Specific-fit replacement with 5-wire harness and 6 terminals
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Robust metal housing and ceramic sensor construction for thermal durability
• Wiring harness included; harness length measures 9.3 in

Product Details

This Bosch Actual OE Oxygen Sensor is engineered for vehicles that rely on wideband feedback for precise fuel control. Bosch pioneered the planar pump-cell wideband design used in modern engine management, and part number 17217 reflects that OE-focused approach for the 2007-2010 Mini Cooper upstream sensor location. The sensor provides the ECU with continuous air-fuel ratio data, supporting stable operation during load changes, cold starts, and high-temperature cycling. This part cross-references 11787590713 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Rough idle or hesitation caused by inaccurate mixture feedback
• Reduced fuel economy from poor fuel control
• Elevated emissions from delayed or inconsistent sensor response

Installation Notes and Tips

Fits 2007-2010 Mini Cooper, upstream. Verify the connector shape, 5-wire harness, and 18 mm threaded mounting before installation. Use the correct oxygen sensor socket and inspect the exhaust bung threads for damage or contamination. Confirm the replacement matches the original wideband sensor location and connector style on your vehicle. Bosch 17217 is a direct-fit replacement for the listed application.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. The Actual OE Oxygen Sensor line is built to OE-proven standards for accurate signal output, reliable heater performance, and consistent operation in demanding exhaust conditions.
