LS3 INTAKE MANIFOLD -LSXR 102MM FITS LS1 LS2 LS 6 Airflow engineers at RHS and the EFI specialists at FAST recently worked hand-in-hand to develop a superior intake manifold for GM LS performance applications. With models available for all the popular LS engines, 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 modification. Regardless of the application, dyno testing has proven these manifolds deliver significant bolt-on performance gains in stock applications and gains upwards of 25+ horsepower in larger displacement or highly modified combinations. 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. |
