The NGK direct-fit oxygen sensor for Mazda 6 (2006–2008) replaces the factory unit and provides continuous closed-loop OBDII feedback to the engine control unit to help maintain optimal engine performance, fuel efficiency and emissions control. It uses advanced ceramic sensor technology with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect the sensing element from poisoning and improve resistance to failure while supporting OE-level fitment.
