A used genuine Audi oxygen O2 sensor (pre-cat upstream), OEM part number 077906265AC, for the right bank. Designed for the 4.2L V8 gas DOHC naturally aspirated engines (4163CC/4172CC) in the Audi A8 Quattro. This upstream sensor monitors exhaust oxygen content before the catalytic converter to adjust the air-fuel mixture. A failing sensor can trigger a check engine light, cause poor fuel economy, or lead to rough running.
