Flat intake manifold gasket it used between the intake manifold runners and the cylinder head on Porsche flat-six engines. Each gasket seals one intake port pair; a complete engine typically uses six of them.
Sold each, typically 6 required per car.
Fits:
Porsche 911 1974 - 1983 - 6pcs required

This gasket provides a gas-tight seal at the intake manifold interface so that all air entering the engine passes through the intended metered path (CIS / fuel injection system).
By preventing air leaks at the manifold flange, it:
• Maintains correct mixture and idle quality
• Supports smooth throttle response and drivability
• Helps avoid lean conditions that can lead to higher combustion temperatures.
Over time, intake manifold gaskets can harden, shrink or crack due to heat cycles, fuel vapour and age. When they fail:
• The engine may draw in unmetered air, causing rough idle, poor cold running or lean mixture.
• You can experience hesitation, popping, or flat spots under acceleration.
• Vacuum leaks can make tuning and diagnostics difficult and may increase fuel consumption.
Replacing old gaskets with fresh restores correct sealing, stabilises idle and mixture, and helps the engine run as intended.
When to replace
Consider replacing the inlet manifold gaskets if:
• You’re rebuilding or refreshing the top end of the engine.
• There are suspected vacuum leaks around the intake manifold.
• The engine has rough idle, hunting, or lean codes/symptoms not traced to other components.
• The original gaskets are visibly cracked, brittle, or oil/fuel soaked.
• You are converting, upgrading or servicing the CIS / intake system on a classic 911 or 930.
