Bosch Premium Original Equipment Oxygen Sensor

The Bosch Premium Original Equipment oxygen sensor line (also called O2 sensor, lambda sensor, or air-fuel ratio sensor) is built to monitor the oxygen content in engine exhaust. It sends accurate data to the engine control unit so the ECU can keep fuel delivery and combustion efficiency on target. Bosch is a leading original equipment supplier of oxygen sensors, and this line is engineered to match OE form, fit and function.

Key Features:

• Original equipment-quality design for dependable, accurate signal output
• Helps maintain proper air-fuel ratio for better fuel economy and lower emissions
• Supports catalytic converter efficiency and overall engine performance
• Precision manufacturing and testing for consistent quality
• Available in upstream and downstream configurations across multiple applications
• Designed for straightforward installation as a direct replacement for the original sensor

A worn or contaminated oxygen sensor can cause a check engine light, rough running, poor fuel economy, and failed emissions tests. Replacing it with a Bosch Premium Original Equipment oxygen sensor helps restore proper engine management and emissions control.
