The NGK direct-fit oxygen sensor for Mazda 3 (2012–2013) provides OE-style oxygen monitoring to the vehicle’s on-board diagnostic system so the ECU can maintain proper air–fuel ratio, support fuel efficiency and reduce emissions. NTK applies advanced ceramic control to these sensors, using a 3-stage contaminant-resistant ceramic element and deposit-trap overcoat to protect the element and improve long-term reliability.
