Airflow engineers at RHS® and EFI specialists at FAST recently worked hand-inhand to develop a superior intake manifold for GM Gen IV performance applications. Designed for L92/LS3/LS7 engines using the latest RHS design technology, the LSXR features a three-piece modular construction to allow for easy disassembly and porting. Extensive testing led to a runner design that was longer and less restrictive, allowing the removal of individual runners for modifi cation. Dyno tests produced gains as large as 16 horsepower and 18 ft/lbs of torque on a stock engine with a mild camshaft. Additional testing on a 500 c.i. engine netted even more impressive gains of 26+ rwhp.
Constructed from advanced polymer material, the LSXR is lighter, stronger and more heat resistant than comparable aluminum intakes. While it features a 102mm air inlet, it can be used with 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment, allowing use of factory accessories without clearance issues.
Note: Throttle body not included.
