The patented LSX™ 92mm Black Intake Manifold from FAST® is the only three-piece Gen III (cathedral port) composite manifold proven to deliver increased performance without compromising bottom-end drivability or high-RPM power. Available for both street and racing applications, the new black intake manifold is an easy bolt-on installation for Gen III (LS1, -2 & -6) engines and is designed to work with the FAST® Big Mouth 92mm Throttle Body™. This intake manifold maintains the performance gains achieved over stock intakes with no loss in drivability or low RPM torque. While the manifold delivers terrific performance right out of the box, it can be ported by the customer for even more flow. As requested by previous LSX™ customers, the intake features the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange with o-ring gasket and threaded insert throttle body mounts that provide increased durability.
