PRODUCT DETAILS

FAST LSXR INTAKE MANIFOLD - SQUARE (LS3) #146102B

FAST™ engineers teamed up with airflow specialists at RHS™ to develop a polymer intake manifold for rectangular port GM L92/LS3 engines. 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.

Constructed from the same advanced polymer material as the 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™, it can also be used with stock or aftermarket 90mm or 92mm throttle bodies. Other features include integrated nitrous bungs and perfect bolt-on fitment that allows the use of factory accessories without modification or clearance concerns.

Features & Benefits:

  • Three-piece, polymer intake manifold for rectangular port GM LS3/L92 engines
  • Advanced polymer material is strong, lightweight, easy to modify and keeps intake charge cool for power enhancement
  • The 102mm throttle body intake diameter works with 90, 92 or 102mm bodies for high flow with a minimum of restriction
  • Gains of 14+ horsepower & 11ft/lbs of torque yet retains all factory fitments and underhood clearance requirements
