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 various thicknesses in both open and ported plenum designs. Gaskets and mounting hardware are included.
