Cold Air Q
All that piece is is a short section of weather stripping which you could find at a hardware store.
i went to home depot in the plumbing section and got some foam insulated tape...its sticky as hell and has some decent cushion to it. i used a couple layers around the back and sides of the airbox. weatherstripping for a car's trunks should be good enough to block off the front of the airbox...a trip to the junkyard would probably not cost you much - or you could jack it from an ******* neighbor's car
