Designed specifically for GM 6.0L and 6.2L Rectangle Port engines where hood clearance is not a concern, the FAST LSXRT‚102mm Intake Manifold follows the path chartered by the original LSXR Intake by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible over stock intake manifolds. Compared to the LSXR intakes, this LSXRT model features a raised throttle body location to clear truck drive accessories.
The LSXRT is constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While it features a 102mm air inlet, it can also be used with stock 87mm, 90mm or aftermarket 92mm-105mm throttle bodies (78mm three-bolt throttle bodies require an adapter plate). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues.
