The NGK direct-fit oxygen sensor for 1994 Buick Regal supplies consistent closed-loop feedback to the engine control unit to help control air-fuel ratio, maintain engine performance and reduce emissions. NTK’s ceramic expertise and OEM collaboration inform the design. The sensor uses an advanced ceramic element protected by a 3-stage contaminant-resistant plasma jet and a deposit-trap overcoat to guard against element poisoning and improve service life.
