Porsche 911 Downstream Oxygen (O2) Sensor

SKU P992-911-O2D
Price

$45.99

The downstream oxygen sensor monitors exhaust gases after the catalytic converter to confirm catalyst efficiency, feeding data back to the ECU. A failing sensor commonly triggers a check engine light without a noticeable performance change.

Built to fit the Porsche 911 (992 generation), matching the OE sensor location and connector for a direct, plug-and-play install.

Made to OEM specifications with a durable sensing element, it's a reliable fix for clearing O2-related fault codes on your 911.

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