LET YOUR ENGINE BREATHE

Performance tunes and hybrid turbochargers add easy power to your Audi twin-turbo 2.9L engine; however, these upgrades demand more airflow. The factory-installed turbo inlet is a significant bottleneck in the stock air intake system that can restrict horsepower. IE's cast turbo inlet is engineered to maximize all available engine space to increase airflow for your turbochargers.

TAILORED FITMENT

Maximizing flow in the constraints of the factory engine bay is the result of the turbo inlet size and shape. Our engineers use high-quality 3D scans and digital flow dynamic software to utilize every millimeter of space for a true-performance design. The result is a perfect fit, a stylish look, and a massive 3.2" effective inner diameter cross-section with an optimized flow path.

CAST ALUMINUM

Our inlet design is manufactured from aircraft-grade aluminum to accomplish the unique bends and shapes required for the cleanest airflow path possible. The casting is then CNC machined to precise tolerances for a perfect fit without clearance issues or the risk of rubbing expensive factory hoses or lines.

PERFECT FIT WITH IE INTAKE

IE cast turbo inlet is the second step to upgrading your intake airflow and has been designed as a direct-install fit with an IE cold air intake system. This combination removes significant airflow restrictions and maintains the largest size possible from the intake to the turbocharger.

Non-IE brand intakes are not guaranteed to be a direct fit and may require custom modifications.

HYBRID TURBO READY

Designed to make installing hybrid turbochargers a simple bolt-in job, the CNC-machined and o-ring sealed adapter flanges are available for the stock turbos (included) or TTE720 aftermarket turbos (sold separately). These adapter flanges always adapt to the turbo inlet size to avoid introducing any restrictions and maintain the largest flow path possible.

TTE720 adapter flanges are currently in production and coming soon. Adapter flanges will be sold separately.

The above gains are a result of various design details:

  1. The 3.2" cross-section inner diameter increases volume for improved airflow efficiency.

  2. The smooth reduction turbo flanges provide a low-turbulence transition from the turbo inlet pipe to the turbo compressor housings.

  3. The unique inlet shape provides an optimized path to quickly channel air from the intake to the turbochargers.

EASY INSTALLATION

Engineered for a perfect and no-fuss fit, the installation process is quick and straightforward using basic hand tools.

Intake install time: 1-2 hours

Excellent fitment

Great fitment and part from IE. This pipe is at least twice the size of the OE pipe so I would like to think its serving a purpose. Also when the car is at operating temp the pipe is cold to the touch so Im sure that helps. My only complaint is the PCV connector on the driver side of the inlet elbow is near impossible to remove without damaging it. However this is not IE's problem. I would say it takes longer to pull off the OE pipe than it does to install the new one. Thanks again for another great product!!

IE Turbo Inlet Pipe for Audi B9 RS5 2.9T

So far so good. I powder coated it because its a rough cast aluminum and I thought it would look better in black. Only thing to note is it does not work with the OEM airbox so i did upgrade to the IE airbox. The inlet pipe is pretty wide so the oem airbox does not fit between the inlet pipe and front of the car.
