These FAST LSX intake manifolds are the only 3-piece Gen III composite manifolds proven to deliver increased performance without compromising bottom-end drivability or high-rpm horsepower. They easily bolt onto GM Gen III (LS1, LS2, and LS6) engines with cathedral port cylinder heads and are designed to work with aftermarket 92mm 4 bolt throttle bodies or stock 90mm electronic drive by wire throttle bodies found on the LS2 GTO's and LS1/LS6/LS2 Corvettes. If you have a cable driven throttle body we offer a kit with a 90mm Accufab billet throttle body.

The new stylish black intake manifolds deliver terrific performance right out of the box and can be ported by the customer for even more flow. As requested by previous LSX customers, the FAST LSX intake manifolds feature 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.
