Single Plenum Intake Kit
  • Polished Aluminum Plenum & Inline Airbox
  • Installation Hardware & Filter Included

    Spectre Air Intake Kits are available for a number of applications and are designed to fit your classic muscle car. The cast aluminum plenum fits carburetors and TBI throttle bodies with a 5-1/8 inch inlet. The plenum attaches to 4 inch outside diameter black MemoryFlex ducting. The air intake ducting connects to an aluminum canister filter housing that shields the air filter from hot air. This is designed to provide more power and quicker acceleration. Additional black MemoryFlex ducting connects to the canister filter housing to provide fresh outside air. A high-flow Spectre HPR synthetic air filter is included. Always check for proper clearance between the neck of the carburetor/TBI and the bottom of the hood before closing the hood.
