The plenum is 2.4 inches tall and attaches to the 4 inch outside diameter aluminum air intake tube. The tube is Spectre part 97990 which makes a 90 degree bend with a 6 inch leg and it can be installed in either direction giving you multiple options for an air filter to be positioned with your engine bay. Always check for proper clearance between the neck of the carburetor/TBI and the bottom of the hood before closing the hood. 2 worm gear clamps and a coupler are included to complete installation.
