Racers and street rodders who want 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. Jomar spacers are also used to fine tune an 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. Jomar also makes high performance stud girdles for several engines.
