Flow balls as used to test airflow on a flow bench. Use them to improve the airflow and find more power. I made these up when I made a set for myself to use. See the photos for sizes. The graduations on the stem are every inch just to give you an idea how far into the port you are. Check online for details on how to use these. Feel free to ask any questions.
