FLOW EQUALS POWER

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 IE Cold Air Intake completely removes the factory flow restriction allowing your stock or aftermarket turbocharger to breathe free and make unrestricted power!

FLOW RESULTS

We know you want the most performance from your investment in aftermarket upgrades and wouldn't sacrifice power for a small, plastic, factory-equipped turbo inlet. IE's engineers have thrown out the factory design and started from the ground up to maximize performance. Utilizing advanced engineering techniques and industry-leading manufacturing processes, IE's Turbo Inlet Pipe takes full advantage of all available space with a unique shape to maximize airflow. This optimized design results in a massive 23% increase in flow over stock!

Back-to-back flow bench testing shows consistent airflow gains over the stock turbo inlet pipe.
The chart above details flow gains (CFM) over stock.

LEADING FEATURES

IE's inlet design has been engineered as the ultimate turbo inlet solution. Only the best materials and design features were used for a high-end fit, function, and ultimate reliability.  

  • 23% higher flow over stock turbo inlet
  • 37.4% higher flow than stock with IE carbon intake (stock turbo)
  • 61.49% higher flow than stock with IE intake (hybrid turbo)
  • 4" effective inner diameter cross-section
  • 85mm inlet side to 66mm turbo side (before adapter plates)
  • Up to 19HP & 21ft-lbs over stock when combined with IE intake
  • Engineered for hybrid turbo flow-support
  • Direct bolt-on fit to stock and popular hybrid turbos
  • Cast aircraft-grade aluminum
  • In-house CNC machined for exact tolerances
  • Maximized shape and size for flow
  • Adaptable for stock or larger turbos
  • O ring sealed turbo flanges for a leak-free seal
  • Perfect addition for your IE Cold Air Intake
  • Stock intake silicone adapter available

DESIGN ELEMENTS

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 3.25" (82.5mm) inner diameter taking up all available space for the most airflow physically possible.

CAST ALUMINUM

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.

STOCK INTAKE ADAPTER

The silicone adapter included is for a direct fit to our IE cold air intake kit (part number IEINCK3). An optional silicone adapter is available to adapt to the stock intake. This may also fit with some non-IE brand intake kits, a direct fit is not guaranteed and modification may be necessary. Not required when installing with an IE cold air intake, sold separately.

INSTALLATION

IE's Turbo Inlet fits Audi B9 S4 & S5 3.0T V6 Turbocharged engines without any modifications or installation hassles. The install process is straightforward and can be done with basic tools. Fitment is not verified on non-IE brand intakes without modification, purchase is at your own risk.

Install time around 1 hour

CNC MACHINED IN-HOUSE

Since the IE inlet is designed to fit the largest space for high-flow as possible, the machine work required for the raw aluminum castings must be done with incredibly tight tolerances. Utilizing our own in-house CNC machines, each individual casting undergoes multiple operations and is verified with a strict quality control process. This ensures every inlet is shipped out with a beautiful machined finish and a precise installation.

Looks good with the intake

This is a huge air flow improvement over stock. Installation was fairly easy besides the one bottom screw on the turbo inlet. It is tough if not near impossible to thread it in without removing the intercooler piping. This combined with the intake makes a noticeable difference in sound and air flow.

Awesome

I did this with the CAI install. While the install is straight forward, Audi don't give you a lot of space to work. So be prepared for some scrapes and scratches. I highly recommend a micro-ratchet to get a T-30 in there.

Quality Unit

Great intake pipe. Much larger than stock. Top fit/finish. The only complaint is the two button-head cap screws you included. I think it'd be much better to include full cap screws instead of the button head screws. At the very least, include one for the bottom bolt. It's hard enough on these cars to get to that bottom bolt...stripping out the head on a button-head screw is almost inevitable.

Paired with the CAI it is a no brainer

Only got 4/5 stars for me. Reason being, the bottom screw on the inlet is very tough to install. I reached out to IE for help but it seems no 'tool' is available and you have to improvise. Good luck, that's all I can say! What should have take a minute to screw took hours. But that aside, it was a doddle to fit and the massive increase in airflow is definitely noticeable when installed and paired at the same time with IE's CAI.
