V9X 3.0 dCi 2 x Intake Manifold Gasket | Renault, Nissan & Infiniti | OEM 1403500Q0B / 8200842632

The intake manifold gasket plays a vital role in maintaining proper airflow between the intake manifold and the cylinder heads. Even a small air leak can reduce engine efficiency, affect turbo performance, and trigger engine fault codes.

The CNM Auto Parts V9X 3.0 dCi Intake Manifold Gasket Set (2 Pieces) is engineered to provide an OEM-quality seal, restoring correct intake pressure and reliable engine performance for Renault, Nissan, and Infiniti vehicles equipped with the V9X diesel engine.

What Does the Intake Manifold Gasket Do?

The intake manifold gasket creates an airtight seal between the intake manifold and the engine.

Its functions include:

• Preventing intake air leaks
• Maintaining correct boost pressure
• Supporting efficient combustion
• Improving engine performance
• Reducing fuel consumption
• Helping the turbocharger operate efficiently

A proper seal is essential for smooth engine operation and maximum power.

Common Symptoms of a Worn Intake Manifold Gasket

A leaking intake manifold gasket may cause:

• Loss of engine power
• Rough idle
• Whistling or hissing noise
• Poor throttle response
• Increased fuel consumption
• Black exhaust smoke
• Check Engine Light
• Reduced turbo efficiency

These symptoms often become more noticeable under acceleration or heavy engine load.

Why Do Intake Manifold Gaskets Fail?

The intake manifold is constantly exposed to heat, vibration, and pressure changes.

Common causes of gasket failure include:

• Heat ageing
• High engine mileage
• Carbon deposits
• Engine vibration
• Incorrect installation
• Reusing old gaskets during repairs

Whenever the intake manifold is removed, replacing the gaskets is strongly recommended.
