FAST 102mm LSXRT Black High HP Runner Intake Manifold (LS3, L99, L92, L76)
0 out of 5
- 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.
