FAST intake
F.A.S.T. 54039
The LSX™ 92mm Intake Manifold from FAST™ is the only three-piece Gen III composite manifold proven to deliver increased performance without compromising bottom-end drivability or high rpm power. The intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines. The new FAST™ LSX™ 92mm Intake Manifold maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low rpm torque. As requested by previous LSX™ customers, the new intake features the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange and o-ring gasket and threaded insert throttle body mounts that provide increased durability.
