Allstar Performance Hi-Flow carburetor spacers isolate your carburetor from the manifold, preventing horsepower-robbing heat transfer and increasing the distance from the bottom of the carburetor to the manifold plenum for better airflow. These spacers are CNC-machined in the USA from a polymer compound that can withstand temperatures of up to 400 degrees F. They're available in open or 4-hole versions for 4150 and 4500 Series Holley and Holley-style carburetors in 1/2 in., 1 in., and 2 in. thicknesses. The tapered, 4-hole spacers have specially contoured holes to increase air velocity under the carburetor. They are not intended for street use.
