Description
Phenolic carburetor spacers are essential for serious carbureted builds—they provide thermal insulation that keeps fuel cooler and reduces vapor lock while maintaining consistent jetting performance under sustained load. The Moroso 1-inch open design fits square-bore applications and installs as a direct bolt-on, making it an efficient upgrade for street and racing engines alike. This is the kind of foundational component that separates dialed-in builds from ones that leave power on the table.
