Define "restriction". These cars don't have airflow problems if that's what you meant. The factory supplied more than enough CFM to keep the NA happy. And despite baking the airbox and filter (which you are still doing with your short ram) the OE pulls ambient air from behind the grill.
Get that filter out into cool air and insulate that intake piping. Then you will be gaining something (assuming there is room for adaptation in the Crossfire's VERY lean OE fuel setup).
