Racers, street rodders, and anyone who wants to maximize an engine's performance, rely on JOMAR Phenolic Carburetor spacers. The advanced phenolic laminate transfers approximately ten times less heat to the carburetor resulting in cooler denser fuel/air mixtures.
In addition, spacers are used to fine tune the engine's performance. A 4-hole spacer will generally improve part throttle operation and help build low and midrange torque, while an open spacer increases plenum volume, adding midrange and top end horsepower. Tapered spacers can offer the best of both worlds-increasing torque, horsepower, and acceleration over the whole RPM range. The correct spacer can show a gain of up to 25+ HP, but spacer selection is highly dependent upon many variables. Talk to your engine builder or give us a call for a recommendation!
