Since almost half the air hitting the intercooler is blocked on a 69 Camaro by the front bumper and valance Pascual and I decided to put an opening in the valance for more air. We are going to add a screen on the backside and a small air diffuser to help the air up a bit into the intercooler. He also completely fabbed in sides to the duct for strength and to look finished as compared to just cutting a hole. He also removed the flattened area at the nose for the front license plate.
