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.

Magnuson Supercharger Kits

Magnuson supercharger kits make power you can live with! Magnuson's powertrain integration technology offers you the ability to have big horsepower and drivability in the same supercharger. This technology recalibrates the engine and transmission control programs to work with the altered induction path and boost pressure of the supercharger. And that produces a seamless and consistent delivery of power over the entire rpm range--not just the high end! For you, that means Magnuson superchargers will boost your power output, and yet run like their factory installed units. Whether you're driving a Corvette or a Cadillac, a Silverado or a Hummer, or a Camaro or a Mustang, Magnuson supercharger kits deliver maximum performance!

Walbro Electric In-Tank Fuel Pumps

Walbro electric in-tank fuel pumps are available in a variety of flow ratings, including pumps that flow significantly more fuel at higher pressure. The outside dimensions, however, of many pumps are compact enough to fit existing hanger assemblies, without modification. All pumping components have been validated to OEM specifications for use in E85/flex fuel applications. Most Walbro in-tank fuel pumps utilize a proven gerotor design. Some high-performance models, including those designed for engines with more than 750 hp, feature a dual-channel turbine design for maximum efficiency in high-pressure and high-temperature applications. The blades feed two high-pressure pumping channels, as opposed to a conventional single-stage pump that uses an impeller with a single row of blades at its outer edge. This innovative design results in improved hot fuel flow, as well as minimal noise and current use, resulting in efficiency that's higher than conventional pumps. Some pumps require modifications to system wiring, fuel lines, and the fuel module, and should be professionally installed. Installation kits including a fuel strainer, fuel hose, harness pigtail, clamps, and wire connectors are sold separately.

S&B Filters Cotton Filter Cold Air Intake Kits

S&B Filters cotton filter cold air intake kits are designed to improve airflow and bring down the temperature of the air that enters your engine. To achieve more airflow S&B oiled cotton filters are built with four or eight layers (for diesels) of the highest-quality cotton gauze. They use deeper and wider pleats with more pleats per filter. Plus, their manufacturing process yields filters with almost no "bleed", creating a greater open surface area. All of this adds up to more surface area per filter, and that means more airflow with excellent protection. All S&B cotton air filters are washable and reusable and will protect your engine from harmful dirt and debris. Your rig will not only gain performance, but also a sporty high-tech appearance under the hood. In addition, the filters and couplers are made with silicone rubber, not urethane, to help ensure they won't degrade or crack and can resist temperatures as high as 400 degrees F. These intake kits are simple to install, and the great looking signature clear lid allows visual inspection of your filter at all times. Remember, there are good air intakes … and then there are the better intakes--demand the better; choose the efficiency and style of S&B Filters cold air intake kits. Features include: * Helps balance air/fuel ratios to improve gas mileage * Specially-crafted cross-linked intake tube minimizes restriction * Custom air box keeps loose dirt and turbulent underhood air out of your intake * Custom-made for your specific year, make, and model * Easy-to-use installation instructions and illustrations * With the included mounting hardware, replaces your stock tract in 30 minutes or less

ACDelco GM Genuine Parts Fuel Injectors

ACDelco GM Genuine Parts fuel injectors are an electro-magnetic valve that meters fuel into the engine's intake manifold or cylinders for combustion, and is a GM-recommended replacement for your vehicle's original component. The engine management computer operates the injector by applying an electric current to the injector solenoid winding—this causes the needle valve to open, and allows the pressurized fuel to be atomized into the intake airstream. These original equipment fuel injectors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors. They are also offered in kits with the necessary parts, such as seals, clamps, and spacer.

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.
