Description
This black plastic adapter is designed for air-cleaner adaptation, matching a 3 1/16" carburetor neck to a 5 1/8" air-cleaner base or opening. It's built for situations where you want to run a larger air-cleaner assembly on a carburetor with a 3 1/16" neck.
Plastic construction with a black finish supports long-term service and clean installation. Confirm gasket sealing, fastener alignment, and added height/clearance before installing, since this adapter adds to your overall air-cleaner stack-up height.
Commonly used to run a large 5 1/8"-neck air cleaner on a carburetor with a 3 1/16" neck, or in custom intake-system builds combining mismatched carburetor and air-cleaner sizes. A 2 5/8" version of this same adapter is also available as a separate listing for smaller single-barrel carburetors.
