BMW F22 M240i Downstream Oxygen (O2) Sensor

SKU F22-M240I-O2D
Price

$134.99

The downstream oxygen sensor sits after the catalytic converter, monitoring its efficiency for the engine computer. A failing sensor commonly triggers a catalyst-efficiency check engine light even with a healthy converter.

This sensor is built to fit the BMW F22 M240i (N55 turbo inline-six), matching the OEM connector and thread pitch.

Reliable, accurately calibrated construction helps eliminate false codes and keep emissions monitoring accurate.

"The socket set is top-tier quality. Heavy-duty steel that handles real torque without slipping. Better than the big box store brands honestly."
