Finishing up the airbox

Once the paint had dried it was time to work out the permanent mounting of the airbox and the top scoop. To keep the heat transfer from the engine bay to a minimum, I installed the trick gold shielding on the bottom of the box. This is probably not necessary given the high front location of the box, but I had just enough laying around for the job...
Trial installation of the box and scoop on the car. I am pretty happy with the lines and gaps. Not quite show car stuff, but certainly nice enough for a race car that I will beat to hell on the track.
Final installation. I affixed the scoop to the top of the box with 6 button head fastners. I used a thin foam one sided tape on the inside of the scoop to seal the perimeter. Once the button heads were drawn down it made a pretty nice seal. The front of the air box was riveted to the head rest bracket. The back is held in place by the rubber rear flange on the K&N filter itself. The hose clamp that holds on the filter also squeezes the filter against the airbox body also making a pretty good seal. To remove the box in the field is easy. Two botton heads hold the head rest on from the front, and remove the clamp from the filter. Then the whole works comes right out of the roll hoop opening from the front. Easy.
Front head on view. Little or no area added to the airstream.
