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 testingled to a runner design that islonger and less restrictive and gives the user the abilityto remove individual runners from the manifold for modification. Constructed fromthe same advanced polymer material as the LSX 92mm Intake Manifold, the LSXR offers a host of benefits overaluminium aftermarket intakes,including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR features a 102mm air inlet that is perfectly suitedto the FAST Big Mouth 102mm Throttle Body, it can also be used with stock or aftermarket90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows accessories without modification or clearance concerns.

Note: Will notfit cathedral port heads.
