Spectre 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 air inlet on the plenum accepts 4 inch outside diameter tubing. Each kit is offered with different options and can be adjusted to your desired position in the engine bay. Always check for proper clearance between the neck of the carburetor/TBI and the bottom of the hood before closing the hood.
