Wilson Manifolds Compound Angle Tapered Carburetor Spacer - Holley 4150 Series - 2" Tall - 4-Hole

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 open spacers have become the standard in NASCAR Cup racing, but are for use in any application where a top quality light-weight billet spacer is desired. Open spacers increase plenum volume and move the throttle blades away from the roof of the runners, allowing the air/fuel mixture to turn more easily into the runners for improved distribution and mixture quality. Open spacers will add mid range and top end hp. Wilson Manifolds is the only manufacturer to produce open spacers in thicknesses from 1" to 2" in 1/8" increments for 4150 carburetors for precise tuning and for applications where hood clearance is at a premium. The engine builder spacer kit includes all nine open spacers (4150) in 1/8" increments and is a must have for any dyno room and for track tuning.
