The first Super Suckers were hand-crafted by Joe Patella for use in Winston Cup before NASCAR outlawed them as an unfair advantage.  Over the years, Joe and his son, Keith, have continued to develop different Super Suckers to satisfy virtually any requirements.  Super Sucker carb spacers increase torque, horsepower, and throttle response.  This is achieved because they increase the airflow through the carburetor by creating a smooth transition from the barrels of the carburetor to the mounting flange on the intake manifold.
