Allstar Performance Carb Spacer 4500 4 Hole 1.00in ALL25994

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 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°F. Available in open or four hole versions for 4150 and 4500 series Holley and Holley style carburetors in 1/2", 1" and 2" thicknesses. Tapered four-hole spacers have specially contoured holes to increase air velocity under the carburetor. * Not intended or recommended for street or circle track use.
