• Narrow-band heated O2 sensor for closed-loop fuel control
• Specific fit with threaded mounting
• 4-wire design with included wiring harness
• Oblong female connector with pin terminals
• 18 mm thread size and 22 mm hex size
• Steel finish with metal housing for high-temperature service
• Wiring harness length: 10 in; overall length: 13.4 in

Product Details

Bosch 16097 uses advanced ceramic sensing elements and optimized heater control to deliver fast light-off and accurate lambda feedback under changing exhaust temperatures. As part of Bosch’s Actual OE Oxygen Sensor line, this sensor reflects decades of OE development and is built to maintain consistent signal quality in demanding thermal and vibration conditions. For drivers searching for a Bosch 16097 oxygen sensor for Pontiac G8 upstream replacement, this part provides the OE-style narrow-band configuration used for precise engine management.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings at the ECU
• Delayed closed-loop fuel control after startup
• Rough combustion control caused by aging upstream sensor output
• Emissions test failures tied to sensor response issues

Installation Notes

Fits 2008-2009 Pontiac G8, Upstream. Confirm the connector shape, 4-wire layout, and 18 mm threaded mounting before installation. Use the correct oxygen sensor socket for the 22 mm hex and route the harness away from exhaust heat and moving components. Bosch 16097 is a direct-fit replacement for the listed application, and the included wiring harness supports OE-style connection routing.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE sensor development. The Bosch Actual OE Oxygen Sensor line is built to the same engineering standards used by vehicle manufacturers, with materials selected for durability in high-heat exhaust environments.
