Genuine Renault Intake Manifold Gasket - Clio 4 RS

Why replace the intake plenum gasket on your Clio 4 RS?

The M5Mt 1.6 Turbo engine in the Renault Clio 4 RS is particularly sensitive to sealing variations in the air intake system. Subjected to high boost pressures and severe thermal stress, the original gasket compresses, hardens, or cracks over time. Keeping a worn intake manifold gasket exposes your engine to serious operational issues:

• Loss of boost pressure: An air leak at the plenum directly reduces turbo pressure, causing a distinct lack of acceleration and throttle response.
• Unstable idle and misfires: Unmetered air entering the system misleads the MAP sensor or air flow meter, causing a lean air/fuel mixture.
• Internal overheating risk: Running a lean mixture increases combustion chamber temperatures, which can damage spark plugs or valves during spirited driving or track sessions.
• Check engine light and fault codes: Frequent illumination of injection warning lights or engine misfire fault codes on the dashboard.

The Assurance of Genuine RENAULT OEM Quality

For such a critical intake component, using low-quality aftermarket alternatives risks rapid deformation. This genuine RENAULT intake manifold sealing gasket is manufactured from high-grade technical elastomer resistant to extreme temperatures and oil vapors.

It ensures a perfect seal between the intake plenum and the cylinder head, fully maintaining factory boost pressures. It is an essential replacement item whenever removing the plenum, servicing spark plugs, injectors, or performing in-depth engine maintenance on your Clio 4 RS 200 or Trophy 220.

Frequently Asked Questions: Replacement and Compatibility

Should this gasket be replaced every time the plenum is removed?

Yes, installing a new intake manifold seal is strongly recommended whenever the plenum is detached. A previously compressed gasket loses its elasticity and can no longer guarantee a reliable seal upon reassembly.

Which vehicles are compatible?

This intake gasket fits all 1.6 Turbo M5M engines powering the Renault Clio 4 RS Phase 1, Phase 2, and Trophy models.
