Trick Flow® GenX® 220 Cylinder Heads for GM LS1
Transform your LS1 into a powerhouse! Trick Flow® GenX® 220 cylinder heads for GM 5.7L LS1 engines are a great value in performance. The cathedral port heads incorporate features of Trick Flow® fully CNC-ported LS heads in a more affordable "Fast As Cast®" version that flows nearly as much air as their competition ported heads. The special Fast As Cast® runner design duplicates the port shape and profile of fully CNC-ported runners, resulting in near-CNC-ported performance for the same price as regular cast cylinder heads. Other features include shallower 13.5 degree valve angles to decrease valve shrouding and increase mid-lift airflow, relocated spark plugs, CNC-profiled combustion chambers with port-to-valve seat blending (bowl blending), improved rocker arm/valve cover clearance, and a rigid casting design. Trick Flow GenX 220 cylinder heads are emissions-legal under CARB E.O. D-747 for 1997-present GM vehicles with 5.7L and 6.0L engines. They are available fully assembled or as bare castings and sold individually.

FAST LSXR Intake Manifolds
The engineers at FAST teamed up with the airflow specialists at RHS to develop a 3-piece, polymer intake manifold. They are constructed from a proprietary advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight and improved strength and heat dissipating characteristics. While they feature a 102mm air inlet that is perfectly suited to the FAST Big Mouth 102mm throttle body, they can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows for the use of factory accessories without modifications or clearance concerns. FAST LSXR intake manifolds' 3-piece modular design allows for easy disassembly and porting. This new design gives you the ability to remove individual runners from the manifold for modification.

FAST LSXRT Intake Manifolds
FAST LSXRT intake manifolds are designed specifically for GM truck engines (4.8L, 5.3L, and 6.0L) and LS1, LS2, and LS6 race applications where hood clearance is not a concern. FAST LSXRT 102mm intake manifolds follow the path chartered by the original FAST LSX Gen III intakes 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. LSXRT's are constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While they feature a 102mm air inlet that was designed for the FAST Big Mouth 102mm throttle body, they 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.

Performance Design Carbon pTR Intake Manifolds
Performance Design Carbon pTR intake manifolds combine high-quality materials into a flexible and powerful tunnel ram architecture. PA6GF30 glass-reinforced nylon (lower) and 5-layer carbon fiber (upper) shells combine for lightweight, strong, and heat-resistant performance. Offering unique modular velocity stacks enabling 6 1/2 in. to 9 in. runners, multiple accessory port and sensor options along with other custom features, these high-performance manifolds offer easy configuring for a variety of hot rod builds, and can even be reversed on the engine. The plenums feature high-strength carbon fiber with high-temperature epoxy for improved strength-to-weight ratio and reduced heat soak to the fresh air charge.
