Walker Products Oxygen Sensor Direct Fit Replacement Sensor

Walker Products direct fit replacement oxygen sensors (also called O2 sensors, air/fuel ratio sensors or lambda sensors) monitor the oxygen content in the exhaust stream and send that data to the engine control module. The module uses it to fine-tune the air/fuel mixture, which helps maintain fuel economy, emissions performance and smooth engine operation.

Key Features:

• Direct fit design that replaces the original sensor without modification
• Built to match the form, fit and function of the original equipment sensor
• Includes the connector and wiring harness configuration appropriate to each application
• Helps restore proper fuel control and reduce the risk of a check engine light caused by a failing sensor
• Supports efficient catalytic converter operation and emissions compliance

Replacing a worn or contaminated oxygen sensor can help restore fuel efficiency, improve drivability and keep emissions systems working as designed. Walker Products is a long-established supplier of emissions and exhaust components for the aftermarket. Select the specific part number in this product line that matches your application.
