Constructed from the same advanced polymer material as the original FAST LSX 92mm Intake Manifold, but now in the popular black color, the LSXR offers a host of benefits over aluminum aftermarket intakes, including lighter weight, increased strength and improved heat dissipating characteristics.

The FAST LSX 102mm Intake Manifold for GM LS3/L92 engines provides bolt-on performance gains without any loss in bottom-end drivability. This manifold features our High HP runners for use in modified street/strip oriented applications.

  • Compatible with interchangeable runner system. Replacement parts available. See 146000B for Upper Shell and 146001 for the lower shell.
  • Removable runners allow for porting
  • Improved throttle body sealing flange and o-ring gasket
  • High quality polymer materials resist the heat sink effecct of aluminum
  • Maximizes potential of other engine performance upgrades like cylinder heads
  • Designed to work with FAST Big Mouth and Big Mouth LT Throttle Bodies
  • Includes stainless steel bolts, threaded insert throttle body mounts and necessary mounting hardware.
  • High HP runners are shorter and straighter than conventional runners to improve high-RPM HP.
