FAST LSX 92MM BLACK INTAKE MANIFOLD (LS1, LS2, LS6) (54039B)


LSX™
For Cathedral Port Heads (LS1, LS6 & LS2)

Forget about inferior knock-offs, the patented LSX™ 92mm Black 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 new black intake manifold is an easy bolt-on installation for GM Gen III (LS1, -2 & -6) engines and is designed to work with the FAST™ Big Mouth Throttle Body™.

The new FAST™ LSX™ 92mm Black Intake Manifold maintains the 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.

  • Black version of original LSX™ intake w/ 92mm opening & added refinements

  • Includes stainless steel bolts, threaded insert throttle body mounts & mounting hardware

  • Incorporates high-quality polymer materials, which resist “heat sink” effect of aluminum

  • Maximizes potential of other popular engine performance upgrades such as cylinder heads

  • Improved throttle body sealing flange & o-ring gasket

FAST LSXr 102MM BLACK INTAKE MANIFOLD (54039B)
LSXR│Cathedral Port Heads (LS1, LS2, LS6)

FAST™ engineers teamed up with airflow specialists at RHS® to develop polymer intake manifolds for GM LS based engines. Testing on a near stock LS7 engine with a Big Mouth 102mm Throttle Body™ produced gains of 16+ horsepower, and 26+ rear wheel horsepower on a 500c.i. engine. The LSXR™ 102mm Intake Manifold features a revolutionary new modular design that allows fast and easy disassembly and features the ability to remove individual runners for porting.

Constructed from the same advanced polymer material as the original FAST™ LSX™ 92mm Intake Manifold, the LSXR™ offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR™ features a 102mm air inlet that is perfectly suited to the FAST™ Big Mouth 102mm Throttle Body™. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

  • Testing shows that a near stock LS7 engine (w/ FAST® 102mm Intake & Throttle Body) produced gains of 16+ horsepower; a 500cid LS based engine gained 26+ rear wheel horsepower

  • Modular design allows fast & easy disassembly & features the ability to remove individual runners for porting
