Spectre's Air Intake Kits are available for a number of applications and are designed to fit your classic muscle car for an original equipment like fit and finish. Manufactured from high quality polished aluminum tubing, the cast aluminum plenum fits carburetors and TBI throttle bodies with 5 1/8 inch inlet offering a low profile design for tight hood clearance applications. (Plenum height is either 2.4 inches or 3.5 inches - always check for proper hood clearance before closing the hood.) Please note, this kit does not include air filters.
