BMW E90 328i Downstream Oxygen (O2) Sensor
SKU E90-328I-O2D
Price
$54.99
The downstream oxygen sensor checks exhaust gas after the catalytic converter to monitor its efficiency. When it fails, expect a check engine light related to catalyst efficiency, even though driveability often feels normal.
This sensor is matched to the BMW E90 3-Series 328i (3.0L I6 N52), fitting the factory downstream exhaust bung and connector.
Built to OEM specs, it's a straightforward way to clear catalyst-related codes and keep your emissions system monitored correctly.
