Bosch Original Equipment Oxygen Sensor

The Bosch Original Equipment oxygen sensor (also called an O2 sensor, lambda sensor or air-fuel ratio sensor) monitors the oxygen content in your engine's exhaust. It sends this data to the engine control unit so the unit can fine-tune the air-fuel mixture. Bosch invented the automotive lambda sensor, and it supplies sensors to many of the world's leading vehicle manufacturers.

Key Features:

• Original equipment quality, built to the same standards Bosch uses for automakers
• Accurate exhaust gas measurement that supports efficient combustion and fuel economy
• Helps keep emissions low and supports proper catalytic converter performance
• Durable construction made to withstand high exhaust temperatures, vibration and corrosion
• Many applications come with a pre-installed connector and wiring harness for a direct-fit replacement
• Available in upstream and downstream designs across a range of applications

A worn or failing oxygen sensor can cause a check engine light, poor fuel economy, rough idle and higher emissions. Replacing it with a Bosch Original Equipment sensor helps restore engine performance and emissions control. Select the child item that matches your application.
