Carburetor Spacer Drag Hi-Flow 0.5 Inch Thick Open Square Bore Plastic Gray Each Allstar Performance

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. Product.
