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