Air intake for Show Planes cowl??

Anybody using the Show Planes cowl? I'm trying to figure out the best method for air intake/filter to the engine. Show Planes doesn't have that part in production yet and I can"t wait months before they do.
I have a Barrett engine with Airflow Performance. The intake to the servo is horizontal opening forward to the cowl front. Thanks!!!

may have a fix
