LSXR│Rectangle Port Heads (LS3, L99, L76)

From FAST:
"FAST" engineers teamed up with airflow specialists at RHS to develop polymer intake manifolds for GM LS based engines. Testing on a near stock LS7 engine with a Big Mouth 102mm Throttle Body™ produced gains of 16+ horsepower, and 26+ rear wheel horsepower on a 500ci engine. The LSXR 102mm Intake Manifold features a revolutionary new 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. 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.

Testing shows that a near stock LS7 engine (w/ FAST 102mm Intake & Throttle Body) produced gains of 16+ horsepower; a 500ci LS based engine gained 26+ rear wheel horsepower.

Modular design allows fast & easy disassembly & features the ability to remove individual runners for porting
