NGK Cadillac CTS 2014-2008 Direct Fit Oxygen Sensor

If your check engine light is on, or you've noticed your fuel economy dropping, your oxygen sensor might be the culprit. This direct-fit NGK oxygen sensor is designed for your 2008-2014 Cadillac CTS, helping to restore proper function to your vehicle's on-board diagnostic system. A failing oxygen sensor can lead to poor engine performance, increased emissions, and reduced gas mileage.

NGK, a major supplier of original equipment sensors, builds this unit with an advanced ceramic sensor element. This element features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor from poisoning, which is a common cause of failure. By providing constant feedback to your car's computer, this sensor helps manage the air-fuel ratio, ensuring your engine runs as efficiently as possible and your catalytic converter works correctly.
