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.

FLOW TESTING

FLOW BENCH GRAPH

Back-to-back flow bench results show consistent CFM gains of up to 39.27% CFM over stock! This flow graph details our turbo inlet's efficiency over the factory parts and capability to provide any required airflow demands from ECU tunes and hybrid turbocharger upgrades.

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

Phenomenal

I was amazing at the difference of the IE Turbo Inlet Pipe vs stock. The stock pipe had such a horrible bend going to the passenger side turbo. There was terrible air restriction. With the IE TIP, it is a great bolt on performance part. The more the RS5 can breathe the better. Two small things, develop a part, like you did for your HPFP, to get to the bottom two Torx 30 bolts. They were an absolute nightmare to remove. Everything is in the way. I finally got it, but wow, what a nightmare for a DIY job. Secondly, please include more than four Torx 25 bolts, I was shaking so badly after fighting to get those 30s off and not lose the bolts, only to find out I wouldn’t reuse them. However, I did use one as I dropped one of the 25s by accident. Love the finished product though. (The part, not the car).

Huge increase in CFM Airflow

Huge difference in comparison to OEM turbo inlets. Much more responsive. Paired it with the IE Carbon Intake!
