Description

The CTS Turbo High-Flow Intake is engineered to enhance the performance of B9 Audi A4, Allroad, A5, S4, S5, RS4, and RS5 models (2017-current). The air then passes through a substantial 6" velocity stack air filter, which is advertised as the largest on the market, to maximize engine performance. The construction utilizes proprietary single-piece molded silicone couplers, including 3.5" 5-ply turbo inlet hoses designed not to collapse, ensuring smooth air entry into the engine. This intake system is designed to deliver increased horsepower and torque across the entire power band, with claimed peak gains of 10-12HP on stock vehicles, and even more on tuned cars. Users can expect less turbo lag and a more aggressive, race-inspired sound, including louder turbo spool and diverter valve release. The kit includes parts for 1.8T, 2.0T, 2.9T, and 3.0T engines, and features a heatshield to maintain low air temperatures. It is noted for its easy installation and perfect fitment. The fitment list includes B9 A4 (2017–current), B9 AllRoad (2017–current), B9 S4 (2018–current), B9 A5 (2018–current), B9 S5 (2018–current), B9 RS4 (2018–current), and B9 RS5 (2018–current).
