Genuine Renault Turbo to Manifold Gasket Megane 4 RS

Why replacing your turbo-to-manifold gasket is critical for your Megane 4 RS

The 1.8 TCe (M5Pt) engine powering the Renault Megane 4 RS subjects its forced induction system to extreme conditions. Positioned directly at the harshest thermal interface, the exhaust manifold to turbocharger gasket endures intense thermal cycles and extreme exhaust gas pressure.

What you risk by keeping a worn or low-quality gasket

Retaining a worn seal or reusing an old gasket during turbo maintenance exposes your engine to significant mechanical issues that degrade driving performance:

• Loss of boost pressure: Even a tiny exhaust leak leads to increased turbo lag and a direct drop in horsepower and torque.
• Damage to surrounding components: Escaping scorching exhaust gases can melt wiring harnesses, nearby hoses, or heat shielding.
• Unwanted noises and fumes: A leak at the manifold flange creates annoying whistling under load and allows exhaust fumes into the cabin.
• Fuel miscalibration and engine fouling: Disruptive air-fuel ratio readings at the O2 sensor mess with ECU calibration, reducing efficiency.

The guarantee of genuine OEM Renault quality

This turbo flange gasket is a genuine Renault replacement part engineered specifically to withstand the intense thermal demands of the 1.8 TCe engine. Unlike low-tier aftermarket gaskets, it ensures controlled torque compression and maximum heat tolerance on both track and street.

Vehicle Compatibility

This sealing gasket is designed for the following models:

• Renault Megane 4 RS 280 HP (Sport and Cup chassis)
• Renault Megane 4 RS 300 Trophy
• Renault Megane 4 RS Trophy-R
