NGK Cadillac XLR 2009-2006 Direct Fit Oxygen Sensor

The ceramic element in this NGK oxygen sensor uses an advanced 3-stage design that acts as a plasma jet and deposit trap. This helps protect the sensor from contamination, which is crucial because oxygen sensors are a key part of your vehicle's on-board diagnostic system. They constantly send feedback to the engine control unit (ECU) to keep the air-fuel ratio just right, which helps your engine run smoothly, get the best possible gas mileage, and keep emissions down.

As the world's largest supplier of OEM oxygen sensors, NGK has a lot of experience here. They control the ceramic element from the raw material all the way to the finished product, using state-of-the-art technology. This means you're getting a sensor that's built to work with your Cadillac XLR's specific needs, helping to alert the OBDII system to any issues with fuel delivery or the catalytic converter.
