I have the Suncoast creations Ram Air hood on my Camaro, but didn't like how pinched the airflow was on the box that came with the hood. So I took a stab at fiberglassing and fabrication and made my own air box and intake. The hood kit used the LT1 radiatior cover for their air box, so this is no LS1 radiator cover. I sanded the center plastic that proruded in the center, then made a box out of plexiglass, and patiently fiberglassed the two parts together. After sanding and using bondo fiberglass filler with more sanding I painted the whole thing with black stone paint to give it a durable finish.
The intake is a 4" polished tube connected to a K&N cone. The entire project only cost me about $80, the most expensive being the K&N of course. You can definately hear the cone through the snouts at idle.
