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.

When it comes to improving your engine’s performance, increased airlow is a key ingredient. The FAST Big Mouth Throttle Bodies for the FAST LSX 92mm & LSXR 102mm Intake Manifolds increase airflow through a series of innovative design changes and a slightly enlarged throttle opening. FAST also invested significant testing & engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation. In addition, these throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. The FAST Big Mouth 92mm Throttle Body will deliver bolt-on GM Gen III (LS-1, 2, 6) horsepower while the LSX is is designed to maximize potential performance upgrades on L92/LS3/LS7 engines.

FAST Precision-Flow Fuel Injectors for GM Gen IV engines are the highest flowing injectors available and are uniquely designed for direct installation into LS2 and LS7/L76/L92-style engines. Available in two different height configurations and a wide range of flow rates, the injectors are correctly sized (shorter than common LS1/LS6 injectors) and feature the correct EV6/USCAR connector, enabling a hassle-free plug-in operation.
