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 LSX Intake Manifolds
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
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.

FAST XFI 2.0/XIM Super Cobra Jet Engine Harnesses
FAST XFI 2.0/XIM Super Cobra jet engine wiring harnesses are designed to integrate with the factory vehicle harness, switch panel, and other components of Cobra Jet engines. It's the same system used by top NHRA and NMCA Stock Eliminator and Super Stock racers such as Anthony Bongiovanni, Gary Richard, Jeff Roell, P.B. Candies, Randy Eakins, Roy Hill, Don Bowles, Susan McClenaghan and Chuck Watson. The wiring harness offers several mounting options for the ECU and ignition module. It also features heavy-duty heat and abrasion-resistant sheathing with heat-shrink-sealed ends on the underhood portion. There's double EMI shielding on critical harness leads, plus durable braided nylon sheathing on the under-dash portion of the harness. It's compatible with Ford 5.4 Modular and 5.0 Coyote engines, either naturally aspirated or supercharged. Each harness includes a detailed vehicle-specific installation guide for integrating the engine harness to the factory switch panel, factory Launch Control/2-Step function, and factory gauges. This allows for simple data-logging of factory-installed sensors like fuel pressure, oil pressure, and brake pressure into the XFI 2.0 ECU. No cutting or trimming is required if the FAST XFI 2.0/XIM Super Cobra jet engine harness is installed as directed. This saves 30-40 hours building labor and results in a neat, factory-appearing installation. Every harness is also 100 percent tested to ensure optimum performance.
