Porsche O2 / Oxygen Sensor (pre Cat), OEM part number 98760612301, is a used genuine sensor removed from a donor vehicle. Also known as an oxygen sensor or upstream lambda sensor, it monitors exhaust gases before the catalytic converter to help the engine control unit adjust the air-fuel mixture. When this sensor fails, common symptoms include decreased fuel economy, a check engine light, rough idle, or failed emissions tests. This sensor fits naturally aspirated H6 engines across Porsche 911, Boxster, and Cayman models.
