IE 3.5" Turbo Inlet, B9 S4/S5/SQ5 EA839 3.0T

One of the highest flowing turbo inlets on the market!

Upgrading our Audi 3.0L turbocharged engine with aftermarket upgrades such as ECU tunes and larger turbos adds fast and easy power, but demands more airflow in return. The factory airbox and turbo inlet are adequate enough for stock power output, but become a large restriction on engines with aftermarket upgrades that can restrict horsepower. Pairing an IE Cast Turbo Inlet Pipe to your upgraded intake completely removes the factory flow restriction allowing your stock or aftermarket turbocharger to breathe free and make unrestricted power!

Tailored Fit

Gaining more flow is all in the size and shape of the turbo inlet pipe within the constraints of the factory engine bay. 3D scans were taken of the engine bay and stock inlet pipe to identify the space available to work in. This allows us to maximize the flow characteristics of the design without running into any clearance issues or rubbing expensive factory hoses or lines. This results in a very large effective 4" inner diameter cross section taking up all available space for the most airflow physically possible.

Cast Aluminum Construction

Designing a performance turbo inlet design is one thing, bringing it to life is another. To accomplish the unique shapes and bends required to achieve the maximum airflow, IE turbo inlets are manufactured from aircraft-grade aluminum castings. This process also results in an attractive finish and incredibly durable product.

Hybrid Support

The IE Turbo Inlet Pipe has been designed with future options in mind. The 3.0T is a very popular platform for modifications and with many owners looking into upgrading the turbocharger for even more power. What's the point of designing a performance turbo inlet capable of hybrid flow rates if it doesn't fit? Our adaptable design utilizes CNC-machined and o-ring sealed adapter rings to fit either the stock or a variety of aftermarket turbos without hassle. Turbo upgrade adapter rings are sold separately.

Slip-Fit Installation

The factory lower bolt location is a very tight fit with little space for tools and can be a frustrating bolt to install, especially with a large aftermarket inlet. For a hassle-free installation, our design features a billet aluminum retainer post that creates a leak-free slip fit for the bottom bolt making the process fast, smooth, and easy!
