Hi-Flow Carburetor Spacers
Specially designed for drag race applications to isolate carburetor from manifold, spacers prevent horsepower-robbing heat transfer and increase the distance from the bottom of the carburetor to the to manifold plenum for better air flow. Spacers are CNC-machined in the U.S from a polymer compound able to withstand temperatures up to 400 degree F. Available in open or four hole versions for 4150 and 4500 series Holley Style caburetors in 1/2", 1" and 2" thicknesses. Tarpered four-hole spacers have specially contoured holes to increase air velocity under the caburetor. Not intended or recommended for street use.
