???? The Invisible Threat: What You Would Lose with a Defective Air Box

The **filter housing** (or **air box**) on your Renault Megane 4 RS is the primary line of defense for your engine against dust and debris. If this part is cracked, warped, or if you use a non-compliant filter, you compromise two vital functions: **filtration** and the **sealing** of the intake circuit. By not replacing your damaged housing with this original RENAULT part, you expose your sports engine to major degradation risks.

The Double Impact on Your Engine: What You Risk Losing

A faulty air filter housing has direct and costly consequences on the mechanics of your Megane 4 RS:

Loss of Longevity (Damage to the Turbocharger)

The primary function of the filter housing is to ensure that only clean air reaches the engine. Poor sealing allows unfiltered air to enter the turbocharger directly. Abrasive particles act like sandpaper on the turbo vanes, leading to premature wear and costly failure. You lose the reliability and lifespan of the heart of your Megane RS.

Compromised Performance and Consumption

The original RENAULT SPORT air box is specifically designed to optimize the air flow necessary for the engine's maximum performance. A cracked or poorly assembled housing can disrupt the air flow measured by the mass air flow sensor. This imbalance can lead to misfires, a noticeable loss of power, and an increase in fuel consumption.

Risks Associated with Using Non-Certified Filters

This product comes with the original RENAULT air filter. Using a non-specific air filter, even with a new housing, can affect filtration or flow. Only the combination of the original filter housing and its original air filter guarantees the level of protection and performance designed by the manufacturer.

The Solution: Original Quality for your Megane 4 RS

This filter housing is an original RENAULT manufacturer part. It is a direct replacement (Plug & Play) for your Megane 4 RS, ensuring a perfect fit and optimal sealing for the engine intake circuit. An essential part for maintaining the **EEAT** score of your maintenance.

❓ Is this air box complete and ready to install? (FAQ)

Yes. The air box is delivered new, including its already fitted original air filter. It is designed to directly replace the old unit and restore the factory filtration performance of your Megane 4 RS.

❓ Does this product improve my engine's performance?
