JET Powr-Flo Carburetor Spacers

These JET Powr-Flo carburetor spacers use aerospace engineering combined with years of experience. They are CNC-machined from billet aluminum and then blue anodized for maximum protection. The JET Powr-Flo carburetor spacers' bore opening is designed to increase the velocity of the airflow into the intake manifold. By delivering the air with more velocity, they allow more into the combustion chamber for a denser air charge. In addition, the increased airflow results in improved overall fuel efficiency. Available in either square bore or spread bore designs, JET Powr-Flo carburetor spacers are sure to give your engine increased midrange horsepower and torque. Show Less
