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.

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 layers (or eight for diesels) of the highest-quality cotton gauze. They use deeper, wider pleats with more per filter. Plus, their manufacturing process yields almost no "bleed", creating a greater open surface area. All of this adds up to more airflow with excellent protection. The filter elements are washable, reusable, and will protect your engine from harmful dirt and debris. Gain performance and a sporty, high-tech appearance under the hood of your rig with an assist from the S&B Filters cotton filter cold air intake kit best suited for your application. More product features, items, and specifications include: * Silicone rubber (not urethane) filters and couplers help ensure they won't degrade or crack, while resisting temperatures as high as 400 degrees F * Helps balance air/fuel ratios to improve gas mileage * Cross-linked intake tube minimizes restriction * Custom air box (where applicable, including some with clear lids) keeps loose dirt and turbulent underhood air out of your intake * Specific year, make, and model design makes them simple to install, with help from the easy-to-use installation instructions and illustrations * Included mounting hardware for replacing your stock assembly in 30 minutes or less in most cases
