Description

Allstar Performance Drag 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 or recommended for street or circle track use.

Additional Information

Drag Race Use Only. Not intended or recommended for street or circle track use. 1-3/4 hole diameter.
