NGK Mazda 3 2013-2010 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 2010-2013 Mazda 3. It's a crucial part of your car's on-board diagnostic system, working to keep your engine running at its best. Unlike older sensors that just signal rich or lean, this wideband sensor gives your ECU a precise, linear reading of your air-fuel mixture. This allows for continuous, fine-tuned adjustments to keep combustion as efficient as possible, which helps maximize fuel economy and minimize harmful emissions.

NGK, a major supplier of original equipment sensors, builds these A/F sensors with a focus on durability. The advanced ceramic sensor element features a 3-stage protective coating that resists contaminants and deposits, helping to prevent poisoning and extend the sensor's life. This attention to material control, from raw components to the finished product, ensures reliable performance for your Mazda 3.
