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 elevates the look of any Golf R, GTI, or S3.
• Velocity Stack Tech: Air is fed through a massive high-flow filter into a CFD-designed Velocity Stack, smoothing out turbulence for sharper throttle response and consistent power delivery.
• Stealth Engineering: Includes a wire-reinforced Silicone Turbo Inlet and a custom Coolant Recirculation Hose that hides ugly vacuum ports and coolant lines for a super-clean, "shaved bay" aesthetic.
• Tool-Less Maintenance: Ingeniously designed with a fully enclosed housing and a Quick-Release Lid, allowing you to pop the hood and swap the filter in seconds without grabbing a toolkit.
• Plug-and-Play Power: Engineered to flow massive amounts of air while remaining compatible with all existing COBB Off-The-Shelf (OTS) Maps—no custom tuning required.
• Premium 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 MQB platform (VW GTI, Golf R, Audi A3, S3) is a masterpiece of engineering, but the factory engine bay is a sea of dull, grey plastic. The COBB Tuning Redline Carbon Fiber Intake is the VIP pass your car deserves. As the flagship of the COBB lineup, this system doesn't just chase horsepower; it chases perfection. The main airbox and integrated ducting are crafted from multiple layers of real 2x2 Twill Carbon Fiber. It catches the light perfectly, withstands the intense heat of a turbo engine bay, and instantly sets your build apart from the crowd.

While the carbon fiber looks expensive, the engineering provides the "go." COBB uses a trumpet-shaped Velocity Stack inside the filter housing. Instead of just jamming a pipe onto a filter, this bell-mouth design organizes the airflow as it accelerates into the turbo inlet. This reduces turbulence, allowing the turbo to gulp down oxygen more efficiently. The result is a car that feels eager and responsive, with a sophisticated induction growl that lets you hear the turbo spool.

European engine bays can be messy with coolant lines and vacuum hoses cluttering the view. COBB cleans this up with clever engineering. The kit includes a custom Silicone Turbo Inlet Hose that features 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 OEM+, but better.

Unlike some "big bore" intakes that wreak havoc on Mass Air Flow readings, the Redline intake is calibrated for precision. It is fully compatible with existing COBB Off-The-Shelf (OTS) Maps. This means you can install the part, flash the standard Stage 1 or Stage 2 map, and drive away with perfect drivability.

The Redline Series resets the bar for what a VW/Audi intake should be. It is designed for the enthusiast who wants the best of both worlds: the show-stopping look of carbon fiber and the race-proven performance of COBB engineering. From the "click" of the tool-less lid to the roar of the induction sound, every interaction with this part is pure satisfaction. Don't just upgrade your car; elevate it with COBB.
