Description

IMPORTANT NOTICE: This is a 3-piece unit designed for the big mouth 102 mm throttle body or a stock throttle body with adapter. For cathedral port heads. Gaskets not included.

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.
