Overview

The IE Turbo Inlet Pipe is a cast aircraft-grade aluminum component designed for the Audi 3.0L turbocharged engine.

This upgrade removes factory flow restrictions, allowing stock or aftermarket turbochargers to breathe freely and achieve unrestricted power. It features a 4" effective inner diameter and is adaptable for stock or larger turbos.
Show original supplier description
The IE Turbo Inlet Pipe is engineered for Audi B9/B9.5 S4 and S5 models equipped with 3.0T V6 turbocharged engines, offering a direct bolt-on fit without modifications. Manufactured from cast aircraft-grade aluminum and in-house CNC machined for precise tolerances, this pipe boasts a maximized 4" effective inner diameter cross-section to significantly increase airflow. This performance upgrade provides a 23% increase in flow over the stock turbo inlet pipe. When combined with an IE intake system, it can yield up to 19HP and 21 ft-lbs of torque. The design incorporates a hassle-free slip-fit retainer post for easier installation, addressing the tight fit of the factory lower bolt location. Fitment is verified for 2017-2024 Audi S4 and S5 models with the 3.0T engine. Installation time is approximately 1 hour with basic tools. It's important to note that fitment is not verified on non-IE brand intakes without modification.
