The NGK direct-fit oxygen sensor for 2005–2008 Buick Allure applications supplies continuous closed-loop feedback to the engine control unit to help control air-fuel ratio, maintain engine performance and support emissions systems. NTK’s ceramic manufacturing control and OEM collaboration contribute to improved sensor designs. The advanced ceramic element includes a 3-stage contaminant-resistant plasma jet and a deposit-trap overcoat to protect against poisoning.
