604 Carb Spacer Simply run a thin beadOur 604 carb spacer is specifically designed to work with the 604 intake. This carburetor spacer, unlike most spacers in the racing industry we are used to, is intake matched, and allows for a smooth transition of air into the intake. The less air flow turbulence you can create, the more power you produce. This spacer comes only in the 1' height.
