WILSON MANIFOLDS 1.50" Open Light Weight 4150
Wilson Manifolds Open Carburetor Spacers
Wilson Manifolds open carburetor spacers have become the standard in NASCAR Nextel Cup racing, but are also for use in any application where a top-quality lightweight 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 horsepower. Wilson is the only manufacturer to produce open spacers in various thicknesses between 1 and 2 inches—for precise tuning of 4150 carburetors and applications where hood clearance is at a premium.
