How Much Do Moroso Wood Design Carburetor Spacers Cost?

Depending on the design and application, Moroso wood design carb spacers range in price between $40 and $50 each.

What Are The Main Benefits of Wood Moroso Carburetor Spacers?

The main purpose of Moroso 1/2 inch carburetor spacers made from wood is to insulate the carburetor and create a barrier from heat that the intake manifold produces. This helps to keep the fuel in the carb float bowls cooler, resulting in more power and performance as well as the reduced chance of vapor lock from boiling gasoline. Spacers also raise the carburetor above the intake manifold. This raises the engine power band slightly, which is favorable in higher-rpm race applications.

How To Install Moroso Carburetor Spacers With A Wood Design

Installation of Moroso wood carburetor spacers is a simple process. If the carburetor is already installed on the intake manifold, it needs to be removed. Next, clean the intake manifold surface where the spacer will make contact to reduce the chance for vacuum leaks. Then install or confirm that the carburetor mounting studs are long enough with a carb base gasket on the intake manifold, the Moroso wood spacer, another carb gasket, and the carburetor in place. More than one spacer can be used, as long as additional carb gaskets are added to each side of the spacers. The carb studs need to protrude from the nuts for proper installation and will need replaced if they are too short. With the proper length mounting studs, the gaskets, spacer(s), and carburetor are then installed with the mounting stud nuts properly tightened until snug. Do not overtighten the nuts as they can damage the aluminum carburetor mounting flanges.
