Bosch 16531 Premium Original Equipment Oxygen Sensor

The Bosch 16531 is a premium original equipment oxygen sensor designed to monitor exhaust gas oxygen concentration and optimize engine performance. This sensor detects the amount of oxygen in your vehicle's exhaust gases and sends a signal to the engine computer, which uses this information to fine-tune the air/fuel mixture to the optimal level for maximum catalyst efficiency and long service life.

Key Features:

• True direct-fit OE connectors and harness for easy installation
• Pre-coated threads with anti-seize compound right out of the box
• 4-wire design with male connector and screw-in attachment method
• Each sensor is subjected to a 1,000 degree Celsius functional test and leak test to ensure environmental and functional robustness
• Robust sensor design increases sensor longevity

Bosch premium oxygen sensors are designed to improve fuel economy while reducing harmful emissions. The typical lifetime of oxygen sensors is 100,000 miles. This is a downstream sensor compatible with select Audi models including A8 Quattro, RS7, S6, S7, and S8 vehicles. OEM part number cross-reference: 4H0906265C.
