The NGK direct-fit oxygen sensor for Buick Allure (2005–2007) supplies continuous closed-loop data to the engine control unit to help control air–fuel ratio, improve fuel efficiency and curb emissions. Developed with NTK ceramic expertise, the sensor includes an advanced ceramic element protected by a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to resist element poisoning and support OE-level application technology.
