Wilson Manifolds Carburetor Spacers have been used by more pole, race, and championship winning teams than any other brand in the world. Our Spacers have been developed through years of testing with the top race teams in nearly all forms of motorsports. Wilson Manifolds offers the largest selection of spacer designs and heights in the industry. This assures that we have a spacer design for virtually all classes of racing that will provide optimum power and distribution. Our precision machining centers allow us to produce the lightest spacer available while still maintaining a high level of structural integrity. This design also reduces the cross-sectional area available for conduction heat transfer from the intake manifold to the carburetor. All Wilson Manifolds spacers, including our tapered spacers, are CNC machined from billet 6061 aluminum for strength, light weight, quality and durability. After machining, a military specification hard coat is applied to each spacer that will not wear off, is scratch resistant, is not affected by alcohol and eliminates corrosion.


Wilson Manifolds Tapered Spacers feature a computer generated variable radius taper design that maximizes the airflow through the carburetor and enhances air/fuel distribution for more horsepower. Part throttle performance and distribution are improved by redirecting the flow pattern created by the partially open throttle blades and gradually reducing the velocity of the air/fuel mixture entering the plenum to allow for a smoother transition into each runner; full throttle performance is improved by increased flow. Our Tapered spacers can increase flow through the carburetor/throttle body by as much as 110 CFM. Wilson Manifolds tapered spacers will increase torque, horsepower and acceleration throughout the entire RPM range.
Wilson Manifolds Tapered spacers will benefit any vehicle that operates under both part and full throttle conditions such as bracket racing using a throttle stop, drag racing, circle track, road racing, off shore power boats, street/strip engines and towing vehicles.
