Drag Race Only Carburetor Spacers. Specially designed for drag race applications to isolate the carburetor from the 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 USA 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 and Holley style carburetors in 1/2 Inch, 1 Inch and 2 Inch thicknesses.

Tapered four-hole spacers have specially contoured holes to increase air velocity under the carburetor.
