FAST LSXrt 102mm High HP Rectangle Port Intake Manifold for LS3/L92 for 16 vehicles

This LSXRT Intake Manifold 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.
