Overview

It properly distributes the air/fuel mixture to the manifold, leading to improvements in throttle response, driveability, top-end horsepower, and torque. This spacer increases air speed from the carburetor base to the intake valve, which can necessitate a change in jet size.

Constructed from polished aluminum, this 1-inch thick spacer features a two-hole design compatible with Holley 2-Barrel carburetors and open plenum manifolds. HVH has been involved in designing high-performance engine components since 1970.

This results in noticeable gains in throttle response, driveability, and overall horsepower and torque. Originally designed by Joe Petelle for Cup engines over 15 years ago, this spacer increases air speed from the carburetor to the intake valve, which may require adjusting your current jet sizes. Constructed from durable, polished aluminum, the SS4412-2AL features a 1-inch thickness and a two-hole design. It is specifically designed for Holley 2-Barrel carburetors and compatible with open plenum manifolds. HVH, High Velocity Heads, brings decades of experience in porting and designing high-performance engine components, ensuring a quality product. While specific vehicle fitment is not detailed here, this carburetor spacer is intended for performance applications where enhanced engine breathing and power output are desired. Its design focuses on maximizing air velocity and fuel draw, contributing to quicker E.T. and lap times on the track.
