Air Cleaner Adapter Ring

The TRANS-DAPT Air Cleaner Adapter Ring (MPN 2176) is a precision engineered carburetor adapter designed for vintage and classic car enthusiasts performing engine modifications or air intake upgrades. This adapter bridges the gap between smaller diameter air cleaners and larger carburetor flanges, making it an essential component for custom intake manifold work, engine swaps, and performance builds where stock air cleaner assemblies no longer fit. Whether you're restoring a muscle car or adapting aftermarket components to an existing engine platform, this adapter ring provides the mechanical bridge needed to maintain proper fuel-air delivery and engine bay aesthetics.

Constructed from durable black plastic, the Air Cleaner Adapter Ring features a 2-5/8 inch air cleaner bore that steps up to a 5-1/8 inch carburetor flange, with a compact 0.75 inch mounting height that minimizes engine compartment intrusion. The tapered ring design ensures a secure, leak-free seal between the air filter assembly and carburetor inlet, preventing unmetered air from bypassing the filter element and compromising air-fuel mixture calibration. The plastic construction offers excellent chemical resistance to fuel vapors and oil mist while remaining lightweight at just 0.23 pounds, reducing unnecessary mass in the intake tract and simplifying installation without requiring complex machining or custom fabrication work.

Mechanics and restoration specialists rely on this adapter for late-model carburetors fitted to classic small-block and big-block engines, as well as fuel-injected-to-carburetor conversion projects where intake geometry differs significantly from original specifications. Installation is straightforward—simply position the ring between the air cleaner base and carburetor top, then secure with existing hardware. The compact 7.8 x 7.9 inch footprint fits most traditional engine compartments without clearance issues, making this adapter ideal for street rods, drag cars, and vintage hot rods where non-OEM air intake components are the norm. Stock up on this essential intake adapter to maintain proper engine breathing during your next modification project.
