Bosch Air Mass Sensor for Porsche 986 Boxster/996 (1999–2005)

This Bosch Air Mass Sensor is a direct-fit replacement for Porsche 986 Boxster and 996 applications listed in the fitment table below. It measures incoming air mass so the DME can meter fuel correctly and maintain stable drivability. 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 weak air-mass signal can cause rough idle, hesitation, lean or rich faults, and inconsistent throttle response. Replacing the sensor with the correct Bosch unit restores accurate airflow measurement.
