BMW Air Plenum Gasket - Genuine BMW 11617834685

Product Information

Genuine BMW intake manifold gasket supplied new and unused. This gasket seals the intake manifold, also referred to as the air collector, to the throttle bodies. Most applications use 10 gaskets per vehicle, making replacement recommended whenever the intake assembly is removed.

Engine Intake Manifold Gasket

An engine intake manifold gasket seals the intake system connection point to help ensure that metered air reaches the engine without leaks. It also helps prevent unmetered air, dirt, and debris from entering the intake tract. Depending on the vehicle and engine design, intake manifold gaskets may be made from paper, composite material, metal layers, rubber, or similar elastomer materials.

It is common practice to replace intake manifold gaskets whenever the intake manifold or air collector is removed. Replacing the gaskets during service helps prevent vacuum leaks, poor sealing, rough running, and airflow related faults after reassembly.

Engine Intake Manifold Gasket Failure Symptoms

• Air leaks caused by heat, vibration, age, or material degradation.
• Swelling or damage from cleaners, solvents, oils, or other chemicals.
• Loss of elasticity, causing the gasket to harden, flatten, or become brittle.
• Check engine light caused by unmetered air or airflow related fault codes.
• Rough running or misfires from a severe intake air leak.
• Oil residue around the intake area from crankcase ventilation vapors and poor gasket sealing.
