OE Aftermarket 140337B005 Intake Plenum Gasket

The OE Aftermarket 140337B005 is a direct-replacement intake plenum gasket designed to restore proper sealing between the upper intake manifold (plenum) and the lower intake manifold. This gasket creates an airtight seal that is critical for maintaining proper engine performance, preventing vacuum leaks, and ensuring accurate air-fuel mixture delivery.

Key Features:

• Direct OE replacement design for proper fit and function
• High-quality gasket material resistant to heat, oil, and engine chemicals
• Prevents vacuum leaks that can cause rough idle, poor acceleration, and check engine lights
• Restores proper sealing between upper and lower intake manifold sections
• Essential component for intake manifold service and repair

This gasket should be replaced whenever the intake plenum is removed for service, cleaning, or repair. Using a new gasket ensures proper sealing and prevents common issues associated with deteriorated or compressed gaskets, including vacuum leaks, reduced engine performance, and increased emissions.
