The intake manifold gasket creates a tight, leak-free seal between the intake manifold and the cylinder head. Its primary job is to prevent air and fuel mixture leaks, maintain proper vacuum integrity, and ensure that each cylinder receives the correct charge of air and fuel during engine operation. Without a proper gasket seal, the engine may pull unmetered air, leading to rough running, poor fuel economy, and reduced performance.

Installed between the intake manifold and the engine head, this gasket:
•  Seals intake ports to prevent vacuum and pressure leaks
•  Maintains proper air–fuel mixture routing into combustion chambers
•  Reduces risk of external leaks that could allow contaminants or hot gases into unwanted areas
•  Helps the engine run smoothly with consistent idle, throttle response, and efficiency gaskets are produced using quality materials that resist heat, pressure, and chemical exposure typical of classic Porsche engines.

Over time, intake manifold gaskets can become brittle, compressed, or degraded due to heat, vibration, and chemical exposure. When a gasket fails:
•  Unmetered air can enter the engine, causing lean conditions
•  Rough idling and hesitation may occur
•  Fuel consumption can increase
•  Vacuum leaks lead to unstable performance

Replacing a worn gasket restores the correct seal, improves overall engine breathing, and helps maintain factory-spec performance.

Replace the intake manifold gasket if you notice:
•  Rough idle or unstable engine performance
•  Sudden decrease in fuel efficiency
•  Visible vacuum leaks or intake noise
•  During intake manifold removal for servicing
•  Engine overhaul or restoration
