WILSON MANIFOLDS CARBURETOR SPACER 4150 / 2.00" OPEN LIGHTWEIGHT
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.
