Integrated Engineering (IE) 70mm Turbo Inlet Pipes

The Integrated Engineering (IE) IEINCY2 turbo inlet pipes are engineered as a direct bolt-on upgrade for 2021-2022 Audi C8 RS6 and RS7 models equipped with an IE air intake system. These pipes boast a substantial 70mm inner diameter, maximizing available space for the highest possible airflow, which is 30% larger than stock. Manufactured from aircraft-grade aluminum castings, these inlets offer an attractive finish and exceptional durability while retaining all factory connections and mounts for a seamless installation. The design supports both stock and hybrid turbochargers, utilizing CNC-machined, O-ring sealed adapter rings for a smooth transition. Stock turbo adapter rings are included with the kit, while hybrid adapters are sold separately. Flow bench testing indicates significant gains, with combined iE intake and inlet upgrades showing up to an 88.46% increase in flow over stock. The installation is estimated to take approximately 1 hour with basic tools and requires no permanent modifications. However, it is crucial to note that these inlet pipes are specifically designed as a direct upgrade for the iE Cold Air Intake System only. Furthermore, 2023 and newer model years are currently non-compatible due to significant changes in the factory PCV system; solutions for these model years are under development. Customers have reported increased turbo noise and a noticeable improvement in engine response and power. While the fitment is generally considered excellent, some users have noted that the larger size can make installation tight.
