NGK Mazda 3 2013-2012 Direct Fit 5-Wire Wideband A/F Sensor

This NGK 5-wire wideband Air-Fuel Ratio (A/F) sensor is a direct fit for your 2012-2013 Mazda 3. As a key part of your car's diagnostic system, this sensor helps keep your engine running at its best by precisely measuring the air-fuel mixture. Unlike older sensors that just signal rich or lean, this wideband sensor gives your car's computer an exact reading, allowing for continuous adjustments to optimize combustion, maximize fuel efficiency, and reduce harmful emissions.

NGK, a major supplier of original equipment sensors, builds these units with an advanced ceramic element. This element includes a special overcoat designed to resist contamination and protect against poisoning, which helps ensure the sensor lasts and performs accurately over time. Because NTK controls the ceramic material from start to finish, they can ensure a well-built component that works reliably with your vehicle's ECU.
