Well cars such as the Impreza,equiped with a Mass Airflow Sensor just don't perform to their best when they dump air to the atmosphere and not back past the sensor.

It WILL cause overfueling,lumpy idle,jerky gearchanges and reduced throttle response.

This type of question is asked soo many times.Perhaps it's about time the manufacters/suppliers of these pleb items come forward and explain to us all the benefits themselves
