Engineering Turbo Inlet Pipe

The Integrated Engineering IEINCK4 is a cast turbo inlet pipe engineered to optimize airflow and performance for your Audi B9 S4 & S5 3.0T turbocharged engines. This results in a significant 23% increase in flow compared to the stock component, with a large 3.25" inner diameter that supports stock or larger turbo configurations. Constructed from cast aircraft-grade aluminum, the IEINCK4 is CNC machined in-house to ensure exact tolerances for a high-end fit and function. The turbo inlet pipe is adaptable for stock or larger turbos, making it suitable for various power goals. This turbo inlet pipe is specifically designed for the Audi S4 2017-2020 (B9) 3.0T turbocharged engines and the Audi S5 2018-2020 (B9) 3.0T turbocharged engines. The included silicone adapter is verified for fitment with the IE Cold Air Intake System only. Fitment with non-IE brand intakes is not confirmed, and modifications may be necessary. IE is developing a silicone coupler for stock intakes.
