Delphi ES10579 Oxygen Sensor Sensor Replacement - O2

The Delphi ES10579 is a direct-fit OE-replacement oxygen sensor (O2 sensor) engineered to restore precise air/fuel ratio feedback to your vehicle's engine management system. Built on over 100 years of original equipment manufacturing experience, Delphi supplies this sensor to the world's top automakers — meaning the same OE-grade engineering and materials are delivered in an aftermarket package.
