The FAST LSXRT 102mm Intake Manifold is designed for GM 4.8, 5.3 and 6.0 truck engines and cathedral port LS1, LS2, LS6 race applications where hood clearance is not a concern. The FAST LSXRT 102mm Intake Manifold follows the path chartered by the original FAST LSX Gen III Intake by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake, on a stock 6.0L engine with a 102mm Throttle body. Similar to the LSXR 102mm Intake Manifold for cars, the LSXRT features the ability to remove individual runners for modification.

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 that was designed for the FAST Big Mouth 102mm Throttle Body, it can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). 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.
