CARB SPACER SQ BORE 1/2in ALLOY OPEN with PORT

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. Holley 4150|
