FAST LSX Intake Manifold Port Gasket Set for

The FAST LSX Intake Manifold Port Gasket Set line offers engine air intake seals (also called intake manifold port gaskets or port seals) for FAST LSX intake manifolds. These seals sit between the intake manifold ports and the cylinder heads. They help keep the intake charge sealed and prevent vacuum leaks in LS-based engines.

Key Features:

• Purpose-built for FAST LSX manifolds: Engineered by FAST as port-to-cylinder-head seals for its LSX intake manifold series.
• Individual port seal design: O-ring style port gaskets provide a consistent seal at each intake port.
• Cathedral-port compatibility: Suited to both GM and FAST cathedral port intake manifold applications, depending on the part number selected.
• Reliable sealing: Helps maintain proper air delivery, steady idle quality and consistent engine performance.
• Brand backing: FAST (Fuel Air Spark Technology) is a trusted name in LS intake manifolds, fuel injection and engine management.

Use these port gaskets when installing a new FAST LSX intake manifold or when replacing worn or leaking seals. Choose the child part number that matches your manifold series.
