FAST LSXR 102mm Intake Manifold Big Mouth Chevy LS3 - Rectangular Port

FAST® engineers teamed up with airflow specialists at RHS® to develop polymer intake manifolds for GM LS based engines. Testing on a near stock LS3 engine with a Big Mouth 102mm Throttle Body™ produced gains of 16+ horsepower, and 26+ rear wheel horsepower on a 500c.i. engine. The LSXR™ 102mm Intake Manifold features a revolutionary modular design that allows fast and easy disassembly and features the ability to remove individual runners for porting.

Constructed from the same advanced polymer material as the original FAST® LSX™ 92mm Intake Manifold, the LSXR™ offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics. While the LSXR™ features a 102mm air inlet that is perfectly suited to the FAST® Big Mouth 102mm Throttle Body™. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

Notes: This is a 3-piece unit designed for the Big Mouth 102mm throttle body or a stock throttle body with adapter. Gaskets not included.
