The NGK wideband air–fuel sensor for Mazda RX-8 (2004–2008) outputs a linear signal that allows the ECU to precisely measure how rich or lean the engine is running and continuously adjust the mixture. NTK controls ceramic production and refines sensor design; the advanced ceramic element includes a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to help prevent element poisoning and improve durability.
