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.

  • 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.
