Modify Engine Air Intake and Filter

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Air filter

To improve engine performance, modify the engine's air intake system. The modification involves adding an extension to the air intake tube and installing a new type of filter. Remove the original air box by taking out the internal part, then create an opening at the front to enhance incoming airflow. Next, modify the extension by bringing the tube inside the air box. After securely fastening the tube with a sturdy metal clamp, attach the new filter to the end of the tube, ensuring it is also secured.
