CTS Turbo High-Flow Air Intake For Audi B9 A4 A5 S4 S5 RS4 RS5 6" Velocity Stack

Unleash the full potential of your Audi’s turbocharged engine with the CTS Turbo High-Flow Intake System (CTS-IT-290R), designed for B9 platform models including the A4, A5, Allroad, S4, S5, RS4, and RS5.

This premium performance intake optimises airflow, reduces turbo lag, and enhances throttle response — all while producing a powerful, sporty sound that amplifies your driving experience.

Engineered to work perfectly with the OEM air scoop, the system channels cold air efficiently through a massive 6” velocity stack air filter and a smooth 3.5” silicone turbo inlet, maximising power gains of up to 12HP on stock engines (and even more on tuned setups).

✅ Key Features:

• 6” Velocity Stack Filter: One of the largest filters available, ensuring maximum airflow and filtration efficiency.

• High-Flow Design: Improves throttle response, reduces turbo lag, and increases overall power output.

• 5-Ply Silicone Couplers: Strong, heat-resistant, and designed to maintain consistent airflow without collapsing.

• Heat Shield Included: Keeps intake temperatures low by blocking excess engine heat.

• Easy Installation: Precision fitment for direct bolt-on install using factory mounting points.

• Aggressive Sound: Noticeable induction roar and amplified turbo spool / diverter valve noise.

• Dyno-Proven Gains: +10–12HP on stock engines; even greater results with ECU tuning.

• Compatible Across Engines: Includes fittings for 1.8T, 2.0T, 2.9T, and 3.0T engines (MAF-less).

⚙️ Application / How to Use:

Install the CTS Turbo High-Flow Intake Kit in place of the factory airbox and intake piping.
It uses the stock air scoop and factory mount points, making installation simple and fully reversible.
No tuning or cutting required — perfect for both stock and tuned B9 Audi models.
