The do88 turbo inlet hose replaces the restrictive original intake hose between the air mass meter and turbo with a larger 3 inch (76mm) bore for freer airflow. It is molded from silicone and reinforced internally with steel wire so it will not collapse under high vacuum. The underside carries a 25mm connection for a recirculating bypass valve.
