    Designed specifically for GM 4.8/5.3/6.0L cathedral port truck engines and cathedral port LS1, -2, -6 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 Big Mouth 102mm Throttle Body™. And 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. Some GM truck models may require the FAST™ 92mm or 102mm throttle body.

    **1999-2002 GM Trucks/SUVs with 3-bolt cable throttle bodies and round plastic fuel rails will require a 92mm or 102mm cable-driven throttle body, as well as OEM fuel rail mounting kit # 111-146030-KIT or billet fuel rail kit # 111-146028-KIT

    **2002-2007 GM Trucks/SUVs with 3-bolt electronic throttle bodies and round plastic fuel rails can re-use the factory throttle body by including throttle body adapter # 146029-KIT. If a Nick Williams 102mm drive by wire throttle body will be used, you must also include the Torque Rush Performance X-Link Module. Also needed will be OEM fuel rail mounting kit # 111-146030-KIT or billet fuel rail kit # 111-146028-KIT

    **2007.5-2013 GM Trucks/SUVs with 4-bolt electronic throttle bodies and square metal fuel rails will reuse the factory throttle body without an adapter, and require OEM fuel rail kit # 111-146031-KIT or billet fuel rail kit # 111-146028-KIT
