LSXRT™ 102mm Truck Intake Manifold (Cathedral Port Heads)

Type: Engine
Vendor: Fuel air spark technology

Description:

LSXRT
Injection Molded Polymer Intake
Cathedral-Port Head Equipped Applications

Designed specifically for GM 4.8/5.3/6.0L cathedral port cylinder head-equipped truck engines and cathedral port LS1, -2, -6 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™. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold 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 OEM electronic 78/90mm or aftermarket 90/92mm throttle bodies (three-bolt electronic throttle bodies require an adapter). Other features include integrated nitrous bungs and a precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues.

  • 25 HP gain when used w/ 102mm Big Mouth Throttle Body™ on a stock 6.0L truck engine

  • Constructed from proprietary precision injection molded polymer;  Lighter than aluminum w/ lower heat soak propensity & greater strength over stock molded intake

  • Innovative multi-layer design w/ removable runners for quick & easy disassembly & porting

  • Integrated nitrous bungs; plug-and-play w/ ZEX™ LSX™ Direct Port Nitrous System

  • Patented Design - U.S. Patent No 8,567,366
