    High HP intake runners from FAST® are now available in a complete all-out race manifold package. Building upon the popular LSXR™ intake manifold, this LSXRT™ version gives LS3 engines with rectangle-port cylinder heads even more plenum volume for all-out racing. Best suited for high-RPM race engines, this manifold creates proven gains of 30+ horsepower over the FAST® LS3 Street Manifold at high RPM. The raised 102mm throttle body location optimizes the larger, less restrictive High HP runner design, creating more power. It also clears truck drive accessories. Learn More
