The Pusher intake manifold for the 7.3L Powerstrokes splits the poorly designed one piece factory manifold in two pieces. This drastically reduces the heat transfer between the hot compressed air exiting the turbo to the inlet Y of intercooled air at the cylinder heads.
The design has been optimized to deliver equalized flow within .1% between the left and right outlets. The factory heater coil port is deleted for increased flow as well. This manifold comes standard with instructions, four 1/8 inch NPT ports and corresponding port plugs.
