50 State Legal Intake - C.A.R.B - E.O. D-279-8

FAST™ engineers teamed up with the airflow specialists at RHS® to develop the LSXR™ Intake Manifolds for cathedral port LS1/LS2/ LS6 engines and rectangular port GM LS3 and LS7 engines. The LSXRT™ Intake Manifold was developed for the GM 4.8/5.3/6.0L cathedral port truck engines and cathedral port LS1/LS2/LS6 race applications where hood clearance is not a concern.

  • Constructed from an advanced polymer material that offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics.
  • 102mm air inlet that is perfectly suited to the FAST™ Big Mouth 102mm Throttle Body™, but the manifolds can also be used with any OEM or aftermarket 4-bolt 90mm or 92mm throttle bodies.
  • Innovative multi-layer design with removable runners for quick and easy disassembly and porting, integrated nitrous bungs and a precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues.
  • When used with a Big Mouth 102mm Throttle Body™, the LSXR™ Intake Manifold produced gains of 16+ Horsepower on a near stock LS7 engine and 26+ Rear Wheel Horsepower on a 500cid RHS® LS Aluminum Block based engine.
