FAST engineers teamed up with airflow specialists at RHS™ to develop a polymer intake manifold for rectangular port GM LS7 engines. Testing on a 500ci LSX engine with LS7 heads and a Big Mouth 102mm Throttle Body™ this manifold produced gains of 26 RWHP over the stock intake. The LSXR™ 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.
Constructed from the same advanced polymer material as the 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™, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.
Notes: Drive-by-wire setups can re-use the OEM GM electronic 4-bolt throttle body. Will not fit cathedral port heads.
