Silicone Adapter

The Integrated Engineering IEINCK4-9 silicone adapter serves as a crucial bridge, enabling the connection of an Integrated Engineering Cast Turbo Inlet Pipe to the factory airbox on Audi B9/B9.5 S4 and S5 models equipped with the 3.0T engine. The adapter is constructed from a strong, multi-ply material ensuring durability and a reliable seal. A direct fit is not guaranteed for other brands, and minor trimming might be necessary. The IE turbo inlet pipe, to which this adapter connects, features a 4" effective inner diameter and an 85mm inlet side to a 66mm turbo side, contributing to a 23% increase in flow over stock. The turbo inlet pipe is crafted from cast aircraft-grade aluminum, CNC machined for precise tolerances, and features O-ring sealed turbo flanges for a leak-free connection. Crucially, this adapter kit does not fit the B9 SQ5. It is designed to fit the following vehicles: Audi S4 B9 (2017-2019) 3.0T, Audi S4 B9.5 (2020-2024) 3.0T, Audi S5 B9 (2018-2019) Coupe 3.0T, Audi S5 B9 (2018-2019) Sportback 3.0T, Audi S5 B9.5 (2020-2025) Coupe 3.0T, and Audi S5 B9.5 (2020-2025) Sportback 3.0T.
