WILSON MANIFOLDS CARBURETOR SPACER - WM-000010

Wilson Manifolds open spacers have become the standard in NASCAR NEXTEL 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.
