Overview

The CTS-IT-290R is a high-flow air intake system designed for B9 Audi models. It is compatible with 1.8T, 2.0T, 2.9T, and 3.0T engines, specifically for MAF-LESS applications.

Show original supplier description
The CTS Turbo B9 Audi A4, AllRoad, A5, S4, S5, RS4, RS5 high-flow intake system is engineered to seamlessly integrate with the OEM air scoop, directing cold air directly into the engine. Air passes through a massive 6″ velocity stack filter, the largest on the market, to maximize engine performance. This intake system features proprietary molded silicone couplers, including 3.5″ turbo inlet hoses with 5-ply construction to prevent collapse, suitable for both 4-cylinder and 6-cylinder engines. It also includes a heatshield to maintain low air temperatures. Key features include a 10-12HP gain on stock vehicles, with potential for even greater gains on tuned cars. The kit includes parts for 1.8T, 2.0T, 2.9T, and 3.0T engines. However, this intake system does not fit cars equipped with a MAF sensor. It is compatible with the following B9 models: A4 (2017-current), AllRoad (2017-current), S4 (2018-current), A5 (2018-current), S5 (2018-current), RS4 (2018-current), and RS5 (2018-current).
