Description

A quality carburetor spacer improves fuel atomization and enhances air velocity through your intake manifold, resulting in better throttle response and more consistent performance across your RPM range. The 1-inch thickness of the 2137 provides optimal plenum volume for Holley 2-barrel carburetors while maintaining structural integrity under high-heat conditions. Installation is straightforward—this is a bolt-on upgrade that requires no fabrication, making it an efficient way to dial in your fuel delivery system.
