Mass air flow sensor screen

It will help stabilize the flow of air through the meter. MAF meters are very sensitive to disruptions in airflow, and anything you can do to help will only result in better performance/reliability/tune-ability. I know not all meters come with screens, but I believe at least some do. I remember reading somewhere about a company that did with theirs... And they were making a big deal out of it... Maybe someone who knows specifically will speak up.
