Throttle Body Transition Casting Porting


    Before air enters the throttle body it must first pass through a cast aluminum pipe which connects the intercooler exit hose to the throttle body. The problem occurs where this pipe meets up with the rubber connetion, there is a lip which poses a rather large restriction to the incoming air. This modification requires grinding and sanding to smooth out this transition to allow for smother airflow.
