BARTOO aluminum air cleaner spacer — 1 inch for 5-1/8" carburetor opening, machined aluminum seal

BARTOO's 1-inch aluminum air cleaner spacer adapts a 5-1/8-inch carburetor opening to raise the air cleaner, improving clearance and simplifying installation while maintaining a sealed fit.

This lightweight, precision-machined spacer is designed for classic and performance engines that use carburetors with a 5‑1/8" flange. Constructed from high-quality aluminum, the spacer replaces or supplements factory risers to provide extra height between the carburetor and the air cleaner element. It’s compatible with many popular carburetor brands and risers, offers straightforward bolt-on installation, and is made to the standard dimensions for a secure seal.

Will this spacer fit my carburetor and air cleaner?

The spacer is made specifically for carburetors with a 5‑1/8" opening and matches common bolt patterns for many aftermarket and OE-style carbs. It fits brands such as Holley, Edelbrock, Rochester, Demon, Carter, and similar units that use the 5‑1/8" flange.

• Designed for 5‑1/8" carburetor openings (bolt pattern compatible)
• Works with Holley, Edelbrock, Demon, Carter, Rochester and like models
• Direct-replacement dimensions for many riser applications

How does the aluminum spacer affect installation and sealing?

Installation is simple: it mounts between the carburetor and air cleaner assembly using the existing bolt locations. The machined faces and consistent thickness promote a reliable seal when used with appropriate gaskets or O-rings, minimizing air leaks when tightened to spec.

• Machined aluminum surface ensures flat mating faces
• Accepts standard gaskets for a leak-free seal
• Bolts on using original carburetor mounting hardware

What practical benefits come from adding a 1-inch spacer?

A 1" spacer gives modest clearance for taller air filters, carburetor linkages, or aftermarket intake accessories without drastically altering intake tract geometry. It can ease hood fitment issues, improve access for adjustments, and reduce heat soak slightly by increasing distance from the intake manifold.

• Creates extra clearance for taller air cleaners or retainer hardware
• Improves access to choke and throttle linkages for tuning
• Helps avoid hood/air cleaner interference on tight engine bays

Is this spacer durable and suitable for engine environments?

Made from high-quality aluminum and manufactured to specification, the spacer resists corrosion and handles typical under‑hood temperatures. Its stable material properties and precise machining make it suitable for daily-driven vehicles and performance builds when installed and sealed correctly.

• High-quality aluminum construction for long-term stability
• Machined to standard tolerances for consistent fitment
• Corrosion-resistant finish for engine-bay durability

Who is this for: This 1-inch BARTOO aluminum spacer is ideal for classic car enthusiasts, hot-rod builders, and anyone replacing or modifying an air cleaner setup on engines that use a 5‑1/8" carburetor flange. It’s a practical choice if you need extra clearance, easier access to linkages, or a direct replacement spacer that fits popular Holley, Edelbrock, Rochester, Demon, and Carter carburetors. Use with appropriate gaskets and follow torque specifications during installation for best results.
