Mercedes-Benz W211 E320 Upstream Oxygen (O2) Sensor

SKU W211-E320-O2U
Price

$89.99

The upstream oxygen sensor monitors exhaust gases right after the engine, letting the ECU fine-tune the air-fuel mixture in real time for efficiency and emissions control.

This sensor fits the Mercedes-Benz W211 E320 3.2L V6 M112, matching the factory connector and thread for a clean swap.

Built to OEM tolerances, it helps restore fuel economy and clears O2-related check engine codes.

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