Engine Intake Manifold

This lower shell replaces the lower shell that came with the LSX 92mm intake manifold.

This upper shell replaces the upper shell that came with the LSX 92mm intake manifold.

FAST is expanding their line of the industry's first polymer tunnel ram-style intake manifold, ideal for generating maximum power in boosted and naturally aspirated GM Cathedral Port LS engines.

Designed for boosted and N/A LS7 engines, the LSXHR 103mm intake is not only rated for 45 PSI of pressure, but also eliminates heat soak thanks to its advanced polymer construction. Gains 30 HP on average over competitors' aluminum intakes.

Designed for boosted and N/A LS3 engines, the LSXHR 103mm intake is not only rated for 45 PSI of pressure, but also eliminates heat soak thanks to its advanced polymer construction. Gains 30 HP on average over competitors' aluminum intakes.

The FAST LSX 102mm Intake Manifold for GM LS1, LS2 and LS6 engines provides bolt-on performance gains w/o any loss in bottom-end drivability.This manifold features our standard design runners for use in mild street-oriented applications.

This lower shell replaces the lower shell that came with the LSXr 102mm intake manifold for LS1, LS2 and LS6 engines.

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.

This upper shell replaces the upper shell that came with the LSXr 102mm intake manifold for LS1, LS2, LS3, and LS7.
