宝马迷你02-08款1.6L氧传感器 11780872674 原厂品质排放达标

BMW MINI 02-08 models 1.6L (R50, R53) oxygen sensor, OEM number 11780872674, directly replaceable with the original, with strong compatibility. This sensor monitors the oxygen content in exhaust gas and feeds back to the ECU to adjust the air-fuel ratio, ensuring combustion efficiency. After installation, issues such as rough idle, high fuel consumption, and excessive emissions can be resolved, especially to avoid failures at inspection due to emissions. If your car shows acceleration weakness, engine warning light on frequently, or black smoke from the exhaust, it is usually due to aging oxygen sensor; replacement is recommended.
