The Moroso Carburetor Air Pan is made for Holley single 4-barrel carburetors with a 5-1/8 in neck, providing a compatible air cleaner mounting platform. It creates a sealed plenum above the carburetor to help manage intake airflow and to accept aftermarket air cleaners that match the neck size. This pan simplifies installation when upgrading intake hardware on a single 4BBL Holley application.
