The engineers at FAST teamed up with the airflow specialists at RHS to develop a 3-piece, polymer intake manifold. They are constructed from a proprietary advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight and improved strength and heat dissipating characteristics. While they feature a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body, they 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 for the use of factory accessories without modifications or clearance concerns. FAST LSXR intake manifolds' 3-piece modular design allows for easy disassembly and porting. This new design gives you the ability to remove individual runners from the manifold for modification.
