This Bosch Downstream Oxygen Sensor is a direct-fit replacement for Porsche 991 and Macan applications listed in the fitment table below. It monitors oxygen content after the catalyst so the DME can track catalyst efficiency and emissions output. Bosch has been a global leader in automotive technology since 1886, pioneering innovations like electronic fuel injection and oxygen (lambda) sensors that shaped modern engine management. Today, Bosch supplies OEM-quality sensors, engine electronics, ignition components, and braking parts found in vehicles worldwide. Known for precision engineering and reliable performance, Bosch parts are built to factory specifications for dependable fitment and long-term durability.

A tired post-catalyst sensor can trigger fault codes, readiness issues, and unstable feedback. A direct-fit Bosch sensor restores the correct connector, thread, and harness layout.
