Specs & Features

• Exotic Materials: Constructed from genuine Hand-Laid 2x2 Twill Carbon Fiber, finished in a high-gloss clear coat that resists heat fade and matches the premium aesthetic of Audi and VW's flagship models.
• Velocity Stack Power: Air is fed through a massive oiled filter into a CFD-designed Velocity Stack, which smooths out turbulence for sharper throttle response and consistent top-end power.
• Stealth Engineering: Includes a custom Coolant Recirculation Hose with an integrated check valve and a wire-reinforced Silicone Turbo Inlet that hides ugly vacuum ports for a super-clean, wire-tucked look.
• Tool-Less Maintenance: Features a smart, fully enclosed housing with a Quick-Release Lid, allowing you to inspect or swap the filter in seconds without digging for tools.
• The Sound of Speed: By removing the baffled factory airbox, this system unleashes the addictive sound of the turbo spooling and the diverter valve venting—refined, but definitely audible.
• Blacked-Out Hardware: Every bracket, clamp, and bolt is finished in Black Anodized Aluminum or black phosphate to maintain a stealthy, cohesive "Redline" appearance.

Product Description

The Audi S3 (8V) is the perfect sleeper—luxury sedan comfort with sports car performance. But pop the hood, and you are greeted by a vast expanse of dull, grey plastic. The COBB Tuning Redline Carbon Fiber Intake is the bespoke suit your engine bay is missing. As the flagship of the COBB catalog, this system is designed for the owner who refuses to compromise. The main airbox and ducting are constructed from multiple layers of real 2x2 Twill Carbon Fiber. It catches the light beautifully, withstands high engine temps, and signals to anyone looking that this car is built with the best.

While the carbon fiber provides the looks, the engineering provides the "go." COBB utilizes a trumpet-shaped Velocity Stack inside the filter housing.

This crucial design element organizes the airflow as it accelerates into the turbo inlet. Why does this matter? Smooth air means the MAF sensor reads accurately, the idle remains silky smooth, and the turbo response is instantaneous. It is refined power delivery that feels right at home in an Audi.

Audi engine bays are generally tidy, but the factory coolant and vacuum lines near the intake can look messy. COBB cleans this up with clever engineering. The kit includes a custom Silicone Turbo Inlet Hose with hidden ports for the air-pump and vacuum lines, effectively tucking them out of sight. They even included a rerouted Coolant Hose with a built-in check valve to move plumbing away from the "beauty side" of the engine. It’s a level of detail that feels like something Ingolstadt should have done at the factory.

The Redline Series resets the bar for what an Audi intake should be. It marries the exotic look of carbon fiber with the reliability of COBB's data-driven engineering. Whether you are attacking back roads in Dynamic Mode or cruising the highway, this intake ensures your S3 breathes deep and looks incredible doing it. Elevate your build with Redline.
