FAST LS3 LSXR Intake Manifold 102mm Flange Black Finish Testing on a stock LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 14+ horsepower and 11+ ft/lbs of torque at the flywheel over the stock intake. The LSXR™ 102mm Intake Manifold features a three-piece modular design that allows easy disassembly and porting. Extensive testing led to a runner design that is longer and less restrictive and gives the user the ability to remove individual runners from the manifold for modification.
