NGK Mazda 6 2005 Direct Fit Oxygen Sensor

If you're working on your 2005-2008 Mazda 6 and need to replace an oxygen sensor, this direct-fit part from NGK is a solid choice. Oxygen sensors are a key part of your car's onboard diagnostic system. They constantly send information to the engine control unit (ECU) about the air-fuel mixture, which helps keep your engine running smoothly, get the best possible gas mileage, and reduce harmful exhaust emissions. When an oxygen sensor isn't working right, your car's computer can detect problems with fuel delivery or the catalytic converter.

NGK is a major supplier of original equipment oxygen sensors, so you know you're getting a part that's made to the same standards as what came on your car from the factory. This sensor features an advanced ceramic element that's protected by a 3-stage plasma jet and deposit trap. This design helps prevent contaminants from poisoning the sensor, which is a common cause of failure. Because NGK controls the ceramic element from the raw material all the way to the finished product, they can ensure a high level of performance and resistance to failure.
