Air Cleaner Spacer - 3/4in

The Edelbrock Air Cleaner Spacer – 3/4in is a precision intake manifold accessory designed for carburetor-equipped engines seeking optimized air temperature and velocity control. As an experienced mechanic and performance builder, you understand that carb flange height directly affects fuel atomization, engine breathing efficiency, and overall tuning characteristics. This 0.75-inch spacer sits between your carburetor and air cleaner, creating critical separation that improves cold-air induction dynamics and allows better fuel mixture uniformity across engine load ranges.

Constructed from durable black plastic, the Edelbrock Air Cleaner Spacer – 3/4in features a 5-1/8-inch carburetor flange that matches OEM and popular aftermarket carb mounting patterns. The 0.75-inch thickness is engineered to position your air cleaner housing at an elevation that minimizes hot-engine compartment air recirculation while maximizing cool-air intake from external sources. This straightforward but essential modification improves volumetric efficiency without requiring internal engine work, making it ideal for street engines, mild performance builds, and restoration projects where factory carburetor setups dominate.

This spacer benefits carbureted four-barrel and two-barrel applications across domestic muscle cars, hot rods, and classic trucks from the 1960s through 1980s. Installation is straightforward: unbolt your existing air cleaner, insert the spacer between the carb and cleaner assembly, and retorque fasteners to factory spec. The lightweight design (0.23 lbs) adds negligible mass while paying dividends in cooler intake charge temperatures and more consistent jetting response across seasonal temperature variations. Verify your specific carburetor flange diameter and air cleaner clearance before ordering to ensure seamless fitment with your existing components.
