Proflow Carburetor Spacer 1/2" Thick Phenolic 4-Port 4150 (PFECS050)

Proflow 1/2" Phenolic Carburetor Spacer - 4-Port 4150

Proflow carburettor spacers offer many advantages. They extend the length of the intake mixture column to improve air/fuel distribution and reduce the fuel temperature inside the carb, resulting in a denser, more powerful fuel charge. They’ll also help with linkage clearance when using custom throttle setups. They’re available in various thicknesses in both open and ported plenum designs. Stud kit and gaskets included
