NGK Mazda CX-7 2009-2007 Direct Fit 5-Wire Wideband A/F Sensor

If you're noticing your Mazda CX-7 from 2007 to 2009 isn't running as smoothly as it used to, or if you're concerned about emissions and fuel economy, a faulty oxygen sensor could be the culprit. This 5-wire wideband Air-Fuel Ratio (A/F) sensor from NGK is designed to be a direct fit for your specific vehicle, ensuring it works seamlessly with your car's onboard diagnostic system.

Unlike older switching sensors that just tell the computer if the mix is rich or lean, this wideband sensor gives a much more detailed, linear output. This allows your engine control unit (ECU) to know exactly how rich or lean the mixture is and make constant, precise adjustments. The result is optimal combustion, better fuel efficiency, and reduced harmful emissions. NGK builds these sensors with an advanced ceramic element that includes a special overcoat to resist contamination and poisoning, helping it last longer.

NGK is a major supplier of original equipment sensors, so you're getting a part that's developed with the same standards as what came from the factory. This sensor is a solid option for restoring your CX-7's engine performance and emissions control.
