Wilson Manifolds Carburetor Spacer - 1.00" 4 Hole 1.680" Bore (750) No Light Weight, No Hard Coat - NASCAR Legal

4-Hole spacers help build low and mid range torque and are particularly useful in applications that require a great deal of part throttle operation. The 4-Hole design improves part throttle performance by redirecting the flow pattern created by the partially open throttle blades. 4-hole carburetor spacers are fully CNC machined from billet 6061 aluminum for durability and light weight. Due to NASCAR rules, BUSCH, Modified, and Re-Max All Pro spacers do not have the hard coating. Also available is a straight bore 2bbl adapter for use in rules restricted classes.
