Allstar Hi-Flow Carburetor Spacers


Allstar Performance
Allstar Hi-Flow Carburetor Spacers

Product images may differ from actual product appearance.

Spacers isolate carburetor from manifold, preventing horsepower-robbing heat transfer while also increasing air flow due to the increase in distance from the bottom of the carburetor to the manifold plenum. Spacers are precision CNC-machined in the U.S. from a state-of-the-art polymer compound and can withstand temperatures up to 400°F. Available in open or four hole versions for popular 4150 and 4500 Holley style carburetors in 1/2", 1" and 2" thicknesses. Four hole spacers are additionally offered with specially contoured holes which helps increase air velocity under the carburetor.
