Product details
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. LSXr 102mm High HP Rectangle Port Intake Manifold for LS3/L92
