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.

These FAST LSX intake manifolds are the only 3-piece Gen III composite manifolds proven to deliver increased performance without compromising bottom-end drivability or high-rpm horsepower. They easily bolt onto GM Gen III (LS1, LS2, and LS6) engines and are designed to work with the 92mm FAST Big Mouth throttle body. The new stylish black intake manifolds deliver terrific performance right out of the box and can be ported by the customer for even more flow. As requested by previous LSX customers, the FAST LSX intake manifolds feature the added benefits of corrosion-free stainless steel assembly bolts, an improved throttle body sealing flange, and O-ring gasket and threaded insert throttle body mounts that provide increased durability.

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.

Standard Motor Products replacement idle air control valves help you get maximum fuel efficiency and power from your engine. A properly operating idle air control valve is an essential component to helping your vehicle run flawlessly. These valves are often referred to as idle air control or IAC valves (GM), automatic idle speed or AIS valves (DCX), and throttle air bypass solenoid or AIR valves (Ford). These idle air control valves are used on both throttle body and multi-port fuel injected engines to regulate idle speed. The IAC valves open a small bypass circuit that allows air to flow around the throttle. Increasing the volume of air that's allowed to bypass the throttle increases idle speed. The engine's computer controls the IAC valves, if idle speed is out of range, and commands the IAC valves to either increase or decrease the bypass airflow. Replace your vehicle's worn or malfunctioning idle air control valve with these reliable Standard Motor Products replacement IAC valves.
