About this part

Product Details

This adapter is made from steel and features a 5/16 inch-18 thread size, which is what most air cleaner assemblies use. It's designed to connect an air cleaner to a Holley HP Series or Demon carburetor. These carburetors often have a different stud size on top than what a standard air cleaner needs, so this adapter bridges that gap. It's a simple, well-built piece that makes sure your air cleaner sits flush and seals properly against the carburetor base.

When you're installing an aftermarket air cleaner on a Holley HP or Demon carb, you'll find that the factory stud might not be the right size for your new air cleaner assembly. This adapter screws onto the carburetor's stud and provides the correct 5/16 inch-18 thread for your air cleaner hold-down nut. It's a small part, but it's essential for getting the job done right and ensuring there are no vacuum leaks around the air cleaner base.
