Performance Stealth Cold Air Intake for Mercedes-Benz C350 (W204) M272

If you own a W204 C350, you know the M272 3.5L V6 is a workhorse, but the factory air box is a restrictive plastic maze designed more for silence than for flow. Over time, those factory plastic clips and accordion tubes can become brittle, leading to potential vacuum leaks and a sluggish feel when you tip into the throttle. Replacing that bulky OEM housing isn't just about looks; it's about letting the engine breathe the way it was designed to.

This Stealth Look intake system replaces the restrictive factory plumbing with high-flow T304 lightweight aluminum piping. By streamlining the path to the manifold, you eliminate the turbulence found in the stock corrugated hoses. The result is a noticeable improvement in how the car reacts when passing on the highway or pulling away from a light. Because the piping features a black powder-coated finish, it maintains an "OEM+" appearance that blends into the engine bay—perfect for owners who want the gains without the flash of polished chrome.

The heart of this kit is the high-velocity washable filter. Unlike the paper filters that clog and require frequent replacement, this unit is designed for longevity, only needing a deep clean every 50,000 miles. It provides the M272 engine with a consistent volume of cool air, resulting in a deeper, throatier tone under load while remaining perfectly civil during daily cruising.

Why You Need This Upgrade

• Enhanced Output: Real-world gains in horsepower and torque by up to 10% by reducing intake restriction.
• Durable Construction: Built from mandrel-bent T304 aluminum to prevent heat soak and resist corrosion.
• Throttle Precision: Improves air velocity to the stock manifold, removing the "laggy" feeling of the factory electronic throttle.
• Long-Term Savings: The included washable filter eliminates the need for disposable paper filters for the life of the vehicle.
• Acoustic Improvement: Provides a refined, sporty growl during hard acceleration without sounding obnoxiously loud.

Installation Notes

This is a straightforward bolt-on project that can be completed with basic hand tools like a socket set and screwdrivers. No cutting or permanent modification to your chassis is required. Pro Tip: We highly recommend disconnecting your battery terminal for a few minutes during the install. This forces the ECU to reset its long-term fuel trims and "re-learn" the new, increased airflow parameters immediately upon the first startup.
