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 LSXHR Intake Manifolds
The FAST LSXHR intake manifolds are available for LS3 rectangular port applications, as well as LS7 raised rectangular port applications. These units are the industry's first polymer tunnel ram-style intake manifolds—and are ideal for generating maximum power in boosted and naturally aspirated engines. Order the model designed for your application. Features include: * Standard "tall" stacks are interchangeable with separately purchased "medium" and "short" stacks to find the most powerful combination * Polymer construction is lightweight and high strength to eliminate power-robbing heat soak commonly found in aluminum intake manifolds * Average 30 hp gain between 5,000 and 7,500 rpm over competitors' high-ram intake manifolds * Rated for up to 45 psi of continuous pressure * Compound fuel injector angle aims spray pattern for ideal atomization, resulting in maximum power production and superior drivability * Reversible top allows for forward- or firewall-facing throttle body installations * Two nitrous nozzle bosses per runner for clean and easy direct port system installations * 103mm throttle body opening can be ported to 105mm

FAST LSXR Intake Manifold Runners
FAST LSXR intake manifold runners will restore proper airflow to your intake for the performance you crave. These replacements are available in three sizes: Standard Street, High HP, or Race versions. The manifolds are designed to give you the ability to remove individual runners from the manifold for modification. FAST LSXR runners are yet another reason the LSXR intake is the only choice for your GM LS3/L99/L76 engines. Order the model recommended for your year/make and engine application.

FAST Intake Manifold Spacers
FAST intake manifold spacers allow you to use standard-style intakes with Edelbrock Tall Deck race blocks. These spacers are CAD-designed by the engineers at FAST and CNC-machined to strict tolerances to fit your tall decks. FAST intake manifold spacers feature a lightweight, scalloped design that provides rigidity and function without adding significant weight. Installation hardware and a spacer-to-head gasket are included.

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.
