Introducing the Oxygen Sensor Upstream Lambda O2 for Buick Envision — a 100% brand-new upstream oxygen sensor designed to deliver precise air-fuel readings before the catalytic converter. This part, with OEM numbers 55489474 and 350-35163, is built to fit Buick Envision 2021–2022 2.0L L4 Turbocharged and a broad family of GM vehicles including Cadillac CT4/CT4, CT5, CT6, XT4, XT5, XT6; Chevrolet Blazer; Silverado 1500; GMC Acadia and Sierra 1500 variants. The sensor uses piezoelectric sensing with a built-in heating element to reach operating temperature quickly for accurate readings from cold starts.

With a direct-fit replacement, it restores proper sensor signals, improving throttle response, fuel economy, and emissions control. Replacing a failing upstream O2 sensor helps protect the catalytic converter and maintain peak engine performance over time.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
