Set of 3 - 4150 - 4 HOLE TAPERED SPACER SET
ALL 3 OF OF FOUR HOLE TAPERED SPACERS 1" , 1.5" AND 2" Part # 004110, 004130, 004150 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. This spacer has 1.75" bore, which is made for a standard 4150 carburetor. We offer the most complete line of 4-Hole Tapered spacers in 390, 4150, 4500, Q-Jet & 2bbl adapters to
