The patented LSX 92mm Black Intake Manifold from FAST is the only three-piece Gen III LS composite manifold proven to deliver increased performance without compromising bottom-end drivability or high RPM power.

For both street and racing applications, this new intake manifold is an easy bolt-on installation for GM Gen III (LS1, LS2 and LS6) engines and is designed to work with the FAST Big Mouth Throttle Body.

The new FAST LSX 92mm Intake Manifold maintains performance gains achieved over stock intake manifolds with no loss in drivability or low RPM torque.

While the new stylish, black intake 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 and o-ring gasket and threaded insert throttle body mounts that provide increased durability.
