Spectre Ultra Low Profile Air Intake Kits are universal and designed to fit a number of applications. Manufactured from high quality polished aluminum, the plenum fits carburetors and TBI throttle bodies with a 5-1/8 inch inlet. The Ultra Low Profile design allows for use on tight hood clearance applications. The plenum is only 2 inches tall and attaches to the 4 inch diameter aluminum air intake tubes. Each kit is offered with different options and can be adjusted to your desired position in the engine bay. Note: Always check for proper clearance between the neck of the carburetor/TBI and the bottom of the hood before closing the hood.
