Beautiful reproduction of the Factory GM Crossram Cowl Plenum air cleaner setup for 1967-1968Z28 Camaros.  This product is not available anywhere else in the world, period!  We made the tooling and reproduction off of an NOS Crossram Cowl Plenum air cleaner that we purchased from Jere Stahl who was given this NOS piece by the late great road racer Mark Donohue in the winter of 1970.  Mark told Jere when he gave Mark the air cleaners that the Penske shop needed room for the new AMC Javelin parts.
