Edelbrock 14" Round Air Filter Element 3" Deep for 5-1/8" Carburetors - Black Finish, Aluminum Housing

The Edelbrock 1223 Pro-Flo is a 14-inch-diameter, 3-inch-deep round air filter element with a black finish designed for use with 5-1/8" carburetors.

This precision-manufactured air cleaner element is built for classic and performance applications that use popular 5-1/8" diameter carburetors — including many Performer, Thunder, Holley, Thermo-Quad, Quadrajet and Carter AFB models. Finished in a durable black and sized to fit a 14" housing, the 1223 Pro-Flo element combines a serviceable paper filtration media with an aluminum housing for reliable operation and straightforward maintenance.

Which carburetors and setups are compatible with the 1223 Pro-Flo?

The 1223 is made to work with 5-1/8" diameter throttle bodies and carburetor bores. It is suitable for most standard-round carburetor applications listed above and pairs with Delbruck-style housings. Confirm clearance for a 14" diameter lid in your engine bay before ordering.

• Designed for 5-1/8" diameter carburetors (Performer, Thunder, Holley, Thermo-Quad, Quadrajet, Carter AFB)
• 14" outside diameter housing — check hood clearance
• Works with Delbruck bases and related mounting hardware

How is the filter constructed and what maintenance does it need?

The element uses multi-layer paper media inside an aluminum housing with a black finish; the 3" depth provides a balance of airflow and contaminant capture. Replace the paper element on a schedule based on driving conditions, and inspect the housing gasket and mounting nut for integrity at each service interval.

• 3" paper filter depth for general performance use
• Aluminum housing for light weight and corrosion resistance
• Routine replacement of the paper element recommended for optimal airflow

Can I use crankcase ventilation with this air cleaner?

Yes — certain Delbruck-style bases include knock-outs to accept crankcase ventilation adapters, allowing you to route PCV or breather lines. The 10" and 14" housings have those provisions; adapters such as Delbruck #1205 are sold separately where required.

• 10" and 14" models include base knock-outs for ventilation adapters
• Crankcase adapter #1205 (sold separately) fits the knock-out provision
• Ensure adapter compatibility with your specific carburetor base

What are the physical dimensions and fit notes I should know?

The element measures 14" in diameter with a 3" paper element depth. Heights for complete air cleaner assemblies are measured from the gasket flange to the top of the retaining nut; dimensions are precise within about 1/8" for proper fitment. Verify mounting stud size and carb flange compatibility before installation.

• 14" outside diameter, 3" filter depth
• Fits 5-1/8" carburetor bores and compatible Delbruck bases
• Dimensions accurate to approximately ±1/8" for reliable installation

Who is this for? The Edelbrock 1223 Pro-Flo 14" round air filter element is aimed at classic car enthusiasts, street-performance builders, and anyone running a 5-1/8" carburetor who needs a straightforward replacement/filter upgrade. It suits owners who prefer a serviceable paper element, want a clean black finish to match under-hood styling, and require a reliable housing that accepts aftermarket ventilation adapters when needed. Before purchasing, ensure your hood clearance and carb mounting match the 14" diameter and 5-1/8" carb flange specifications.
