NGK Cadillac XLR 2009-2006 Direct Fit Oxygen Sensor

This NGK oxygen sensor is designed to fit your 2007-2010 Cadillac STS, 2007-2009 Cadillac SRX, or 2006-2009 Cadillac XLR. As a crucial part of your vehicle's on-board diagnostic system, oxygen sensors work to keep your engine running at its best. They provide constant feedback to the engine control unit (ECU) to manage the air-fuel ratio, which helps maximize fuel efficiency and reduce harmful emissions. If your check engine light comes on, an oxygen sensor issue could be the cause, potentially indicating problems with fuel delivery or the catalytic converter.

NGK, a leading manufacturer of OEM oxygen sensors, builds these units with an advanced ceramic sensor element. This element features a 3-stage contaminant-resistant plasma jet and a deposit trap overcoat. This design helps protect the sensor from poisoning by contaminants, ensuring it can accurately monitor exhaust gases over time. Trust NGK's expertise, as they are a ceramics company at their core, controlling the ceramic element from raw material to the finished product.
