The Boxster scoops would fit right into the GL. I wonder if they would function well with the aerodynamics of the side of a Beetle. I hate to submit hearsay, but I have heard that there is a low pressure zone in front of the rear fenders. Does anyone know if this is true? Are the Remmele scoops longer so they catch air from forward of this low pressure area (if it exists)?
