The patented FAST™ LSX™ 92mm Intake Manifold is a 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 GM Gen III (LS1, -2 & -6) applications, this intake manifold is a bolt-on installation and is designed to work with the FAST™ Big Mouth 92mm Throttle Body™. The FAST™ LSX™ 92mm Intake Manifold maintains the performance gains achieved over stock intake manifolds with no loss in drivability or low rpm torque. While it delivers terrific performance right out of the box, it can be ported for even more flow. 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.
• Increases horsepower over stock manifold with no loss of drivability or low rpm torque
• Incorporates high-quality polymer materials which resist "heat sink" effect of aluminum
• Maximizes potential of other popular engine performance upgrades such as cylinder heads.

Fast 102mm Manifold
Airflow engineers at RHS® and EFI specialists at FAST™ recently worked hand-inhand to develop a superior intake manifold for GM Gen IV performance applications. Designed for L92/LS3/LS7 engines using the latest RHS® design technology, the LSXR™ features a three-piece modular construction to allow for easy disassembly and porting. Extensive testing led to a runner design that was longer and less restrictive, allowing the removal of individual runners for modifi cation. Dyno tests produced gains as large as 16 horsepower and 18 ft/lbs of torque on a stock engine with a mild camshaft. Additional testing on a 500 c.i. engine netted even more impressive gains of 26+ rwhp. Constructed from advanced polymer material, the LSXR™ is lighter, stronger and more heat resistant than comparable aluminum intakes. While it features a 102mm air inlet, it can be used with 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment, allowing use of factory accessories without clearance issues.
• Designed for GM L92, LS3 rectangle & LS7 raised rectangle port heads
• 16+ hp gains with stock displacement & 26+ rwhp with larger cubic inch
• Removeable runners for easy porting
• Perfect bolt-on fitment allows for the use of OEM accessories
