BARTOO Aluminum Air Cleaner Spacer for 5-1/8" Carburetor Opening — 1/4" Thick, Precision-Machined Seal

BARTOO’s 1/4" aluminum air cleaner spacer provides a lightweight, leak-resistant separation between the carburetor and air cleaner for engines using a 5-1/8" carburetor opening.

This precision-machined spacer is made from high-grade aluminum and designed to fit popular carburetors with a 5-1/8" opening, including Holley, Edelbrock, Rochester, Demon and Carter styles. It installs between the carburetor and the air cleaner or intake riser to provide consistent sealing, a little extra clearance for linkage or fuel lines, and a tidy finished look under the hood. The BARTOO spacer is a direct-replacement style component intended for classic builds, restomods, and routine maintenance projects.

How does this spacer improve the fit of my air cleaner?

The spacer fills the gap between a 5-1/8" carburetor flange and an air cleaner base or riser, creating a uniform surface that helps align hardware and softens clearance conflicts. Its thicker profile can prevent contact between the cleaner and throttle or fuel parts while keeping mounting studs straight.

• Precise 1/4" height for measured clearance.
• Milled inner opening matches standard 5-1/8" carb flanges.
• Prevents rubbing of linkage and fuel lines.
• Provides a stable base for air cleaner mounting studs.

Will this spacer work with my carburetor brand and intake setup?

BARTOO engineered this spacer to be compatible with many common carburetor brands that use a 5-1/8" opening, including Holley, Edelbrock, Rochester, Demon and Carter. It also suits many stock and aftermarket risers for small- and big-block Chevy and other V8 engines when the flange diameter matches.

• Fits Holley, Edelbrock, Demon, Carter, Rochester and similar 5-1/8" carbs.
• Works with many SBC/BBC risers and aftermarket intake manifolds.
• Standard bolt pattern accommodates common stud placements.
• Direct-replacement dimensions for straightforward swaps.

How easy is installation and what tools are required?

Installation is straightforward and typically requires only basic hand tools — remove the air cleaner, set the spacer over the studs or flange, and reinstall the air cleaner. The spacer’s design emphasizes a good seal and simple alignment so you can complete the swap without specialized equipment.

• Standard wrench or socket for air cleaner nut removal and reinstallation.
• No gasket often needed if mating surfaces are clean and flat.
• Can be used with existing studs, wing nuts, or air cleaner mounts.
• Quick, reversible upgrade for testing fit or clearance.

Who is this for? The BARTOO 1/4" aluminum air cleaner spacer is aimed at automotive enthusiasts, restorers, and DIY mechanics who need a reliable, OEM-compatible spacer for carburetors with a 5-1/8" opening. It’s a practical part for anyone refreshing an older engine bay, correcting clearance between carburetor and cleaner, or seeking a durable aluminum spacer that matches common Holley, Edelbrock, Carter and Rochester setups without extra machining or modification.
