The Speedmaster PCE120.1001 is a 2-inch open-design aluminum carburetor spacer engineered to increase plenum volume between your carburetor and intake manifold. The open spacer configuration promotes improved fuel-air mixture velocity and distribution, helping to broaden torque and power delivery across the RPM range.
Constructed from aluminum for a lightweight, corrosion-resistant build, this spacer is a straightforward bolt-on addition to your fuel system. The 2-inch height provides a significant plenum increase, making it a popular upgrade for street performance and racing applications running a compatible 4-barrel carburetor setup.
