FAST LSXRT INTAKE MANIFOLD,BLACK GENIII,102MM

Brand New Fast LSXRT 102mm Intake Manifold for GM 4.8, 5.3, & 6.0L Cathedral Port Truck/SUV Engines (Part #146602B).

Designed specifically for GM 4.8/5.3/6.0L cathedral port 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 Big Mouth 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. Some GM truck models may require the FAST 92mm or 102mm throttle body.

Note: If using OEM fuel rails and injectors part #146030-KIT or #146031-KIT is required for proper installation. For rectangle port cylinders use part #146105B.

Compatible with:

• GM 4.8, 5.3, 6.0L Cathedral Port Truck Engines
