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.

This intake works with "cathedral" port cylinder heads.  LS2 vehicles can re-use your existing oem fuel rail and throttle body.  LS1 and LS6 vehicles will require pn:  146021-KIT if OEM style fuel rails are desired.  Intake port seals pn: 146203-8 are not included.
