FAST LSXR 102mm RACE Intake Runners (GM LS3)

Two new state-of-the-art runner sets build upon our patented removable runner design. LSXR 102mm Intake Manifolds from FAST now have the capability to shift torque and horsepower gains to a higher RPM than the original version, making them the most flexible options on the market.

High HP and Race versions are now available. These manifolds and complementing runners are designed specifically for LS3, L99, L76 and L92* engines that are built for high-performance applications. The High HP Runner Set is based on Daytona Prototype intakes and utilizes newly designed runners. They are shorter and straighter than previous market offerings, specifically to improve high-RPM horsepower and torque in vehicles with added performance modifications. The High HP version has been proven to make 20+ additional horsepower over the original LSXR manifold with a 500-1000 RPM shift up in peak horsepower on LS3 performance engines. The Race Runner Set features a short and straight runner design that rivals aluminum four-barrel intakes for horsepower potential. This manifold setup utilizes a race runner engineered for all-out high-RPM performance. It is ideal for vehicles with serious performance modifications and race converters. The Race version provides a 35+ horsepower gain with a 500-1000 RPM upward shift in peak horsepower for all-out race vehicles.

The runners are interchangeable and available in kits so manifolds may be configured as the original LSXR with standard street runners, or the new High HP or Race models. FAST LSXR Intake Manifolds are available in a popular black finish and are compatible with all FAST Big Mouth Throttle Bodies and fuel rails.

*L92 requires engine accessory modifications.
