FAST LSX Intake 92mm 54039.

New intake includes refinements such as enlarged throttle body opening, higher strength polymer manifold materials and improved throttle body sealing flange and o-ring gasket

Forget about inferior knock-offs, the patented 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. For both street and racing applications, the intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines and is designed to work with the new FAST™ Big Mouth Throttle Body™. In an effort to improve on the previously successful LSX™ Intake Manifold introduced three years ago, the 92mm manifold has received a host of feedback-driven refinements and a larger throttle opening to match the newly released FAST™ Big Mouth™ 92mm throttle body.

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. While the new FAST™ 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 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.
