FAST 146003-1 LSXR 102mm Intake Manifold Port Seal for LS3

The FAST 146003-1 intake manifold port seal is designed specifically for use with FAST LSXR 102mm intake manifolds on LS3 engine applications. This precision-engineered seal creates a reliable gasket between the intake manifold ports and cylinder head mating surfaces, preventing vacuum leaks and ensuring optimal engine performance.

Key Features:

• Designed for FAST LSXR 102mm intake manifolds with LS3 cylinder heads
• Precision-cut to match port dimensions for proper sealing
• High-temperature resistant material withstands engine heat cycling
• Prevents vacuum leaks that can cause rough idle and performance loss
• Essential component for intake manifold installation or rebuilds

This seal is a critical component when installing or servicing FAST LSXR intake manifolds, ensuring a proper seal between the manifold and cylinder heads. Proper sealing prevents air leaks that can lead to lean air-fuel ratios, rough engine operation, and reduced performance.
