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 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.
Now available for LS3, L76, L92 and L99 rectangle port applications is a High Horsepower version of the LSXR™ Intake Manifold. With shorter and straighter runners than the original LSXR™, the High HP intake can make up to 20+ more horsepower than the original. Runner sets can also be purchased separately.
