Wiring Harness, Heated Oxygen Sensor, Regal

Improves idle

Quicker and more accurate emission readings over unheated sensors

This heated oxygen sensor kit consists of pre-installed connectors eliminating the need to cut any wires. Once installed, heated oxygen sensors reach normal operating temperature quicker than unheated sensors which results in your engine's computer minimizing "idle hunting" and an improved idle overall. This leads to a longer life for catalytic converters and oxygen sensors alike. Includes a four-wire oxygen sensor.
