Mopar Performance Oxygen Sensor

The Mopar Performance Oxygen Sensor (also called an O2 sensor, air-fuel ratio sensor or lambda sensor) is a genuine Mopar replacement part. It monitors the oxygen level in the exhaust stream. It sends that data to the engine control module so the module can adjust the air-fuel mixture.

Key Features:

• Genuine Mopar part built to OEM design specifications for consistent fit and function
• Monitors exhaust oxygen to help support engine performance, fuel efficiency and emissions compliance
• Made with durable materials to withstand high exhaust temperatures and harsh operating conditions
• Connector design supports stable electrical connections and dependable signal transmission
• Available in upstream (before catalyst) and downstream (after catalyst) positions, with left and right side options, across the product line
• Bolt-on installation, with no modifications needed

A worn or failing oxygen sensor can cause poor fuel economy, rough running and a check engine light. Replacing it with a genuine Mopar sensor restores accurate exhaust monitoring. It also helps keep the emissions control system working as designed.
