Product Details

Features

  • Chrome steel flat base for a clean engine-bay finish
  • Base only — pairs with a compatible top and filter for a full assembly
  • Compact 6" size for tunnel ram or small single-carb setups
  • Filter sits raised 3/4" for carburetor and clearance management

Description

This chrome steel flat base is built for universal carbureted air-cleaner applications on compact 6" round assemblies, commonly used as individual filters on dual-quad tunnel ram intake setups or small single-carburetor applications. It's built as a base-only component, so it requires a separately purchased compatible top and filter element to form a complete air-cleaner assembly.

The flat base design places the filter raised 3/4" above the base, which helps manage carburetor clearance, overall air-cleaner height, and installation layout. Steel construction with a chrome finish supports stable mounting and a clean engine-bay appearance. Neck flange is 5 1/8", sized to fit carburetors with a 5 1/8" neck diameter.

Before ordering, verify filter height, top fitment, and hood clearance, and confirm throttle linkage clearance, breather routing, fuel-line clearance, and stud length for final assembly.


Applications

Q&A

What's the neck flange size on this base?
This air cleaner base features a 5⅛-inch neck flange, designed to fit carburetors with a 5⅛-inch air horn diameter.

Does this include the top and filter, or just the base?
This listing is for the air cleaner base only. A compatible top and filter element must be purchased separately to complete the air cleaner assembly.

What's this base typically used for?
This base is commonly used as an individual air cleaner base for dual-quad tunnel ram intake setups, where each carburetor uses its own compact air cleaner assembly. It can also be used on compact single-carburetor applications.

What does "filter raised 3/4"" mean?
The flat base positions the filter element ¾ inch above the base, affecting the overall assembled height and available hood clearance. Be sure to account for this when measuring your installation.

Do I need two of these for a dual-carb tunnel ram setup?
Yes. Dual-quad tunnel ram intake manifolds typically use one air cleaner assembly per carburetor, so you'll need one base for each carburetor.
