  RHS Intakes & Throttle Bodies
FAST LSXR Intake
GM L92/LS3/LS7 - 102mm Intake Manifold

Designed for GM L92/LS3/LS7 engines using the latest RHS® design technology, the LSXR™ features a three-piece modular construction to allow easy disassembly & porting. Extensive testing led to a longer, less restrictive runner design, allowing removal of individual runners for modification. Dyno tests with a Big Mouth 102mm
Throttle Body™ produced gains as large as 26+ horsepower & 25+ ft/lbs of torque at the flywheel.

Constructed from advanced polymer material, the LSXR™ is lighter, stronger and more heat resistant than comparable aluminum intakes. While it features a 102mm air inlet, it can be used with 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs & perfect bolt-on fitment, allowing use of factory accessories without clearance issues.

FAST Big Mouth Throttle Body
FAST™ Big Mouth Body™ (92mm or 102mm)

When it comes to improving performance, increased airflow is a key ingredient. Available in 92mm or 102mm diameters, the Big Mouth Throttle Body™ increases airflow through a series of innovative design changes and slightly enlarged throttle opening. Significant testing and engineering was conducted to optimize cross-sectional flow and eliminate airflow turbulence, especially at part-throttle operation. The throttle blade’s increased thickness eliminates deflection, especially in boosted applications. To improve throttle response, the blade pivot is offset, while the beefed up linkage and dual throttle spring mechanism ensure total throttle control.
