NGK Mazda CX-7 2012-2010 Direct Fit 5-Wire Wideband A/F Sensor

The advanced ceramic element in this NGK wideband Air-Fuel Ratio sensor is built with a 3-stage contaminant-resistant plasma jet and deposit trap. This design is key to protecting the sensor from poisoning, which can happen with other types of sensors. For your 2010-2012 Mazda CX-7, this means a more reliable part that helps keep your engine running smoothly.

As a wideband sensor, it does more than just tell the ECU if the mixture is rich or lean; it provides a linear output signal. This allows the engine control unit to make very precise, continuous adjustments to the air-fuel mixture, keeping it as close to stoichiometric as possible. This precise control is what helps maximize fuel efficiency, reduce harmful emissions, and maintain optimal engine performance.

NGK is a major supplier of original equipment oxygen sensors, so you're getting a part designed with OE application technology. Trusting a well-known ceramics company like NTK means you're getting a part that's controlled from raw material to finished product, ensuring it fits right and performs as expected for your CX-7.
