Aeroflow Performance cast aluminium LS2 valley plate is perfect for those that have been converted from EFI to Carburetted applications. This valley plate does not feature any provision for the knock sensor which become no longer necessary when switching to a carburettor application or when moving to a dual knock sensor setup on EFI applications. These valley plates are machined smooth on the underside, allowing for the elimination of Displacement-On-Demand (DOD) or Active Fuel Management (AFM). THESE MUST be blocked off when using this valley plate (delete plugs sold separately AF3000-1009). Designed to be low profile that will eliminate any fitment issues with factory and aftermarket intakes and still take the factory gasket which is included in the is kit. They can be used on factory and aftermarket GM LS2 style engine blocks. Available in either a finned or trussed style design in both natural cast and black finish. Each valley plate includes a new gasket and new mounting bolts.
