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 millimetre 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 aluminium 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:
- The 3.2" cross-section inner diameter increases volume for improved airflow efficiency.
- The smooth reduction turbo flanges provide a low-turbulence transition from the turbo inlet pipe to the turbo compressor housings.
- The unique inlet shape provides an optimized path to quickly channel air from the intake to the turbochargers.

Dogs love it, but it lasted 10 minutes
Color: Blue Yellow, Pattern Name: Alligator
Five stars for the dogs both loving this thing. I have a Catahoula/pitbull and a Great Pyrenees/Red Heeler. They absolutely loved this toy but it only lasted about ten minutes before it was pulled apart and losing its innards. They didn’t really care - they each took half and proceeded to tear it to shreds with great joy. Two stars for durability, but since they’re big dogs who are happiest when chewing on things I figure the toy deserves to be rounded up from a three to a four. Small dogs probably would still love it without the strength to yank it apart so quickly.

Dogs both love it

Dogs are obsessed with this, somehow has not been gutted yet. Long enough that they can both play with it. Neck not as stretchy as I envisioned but it’s fine.

Not worth the money
Color: Green, Pattern Name: Dinosaur
Thought it would be larger as it states LARGE-it was not- it is not interactive - also states that but it is not - so value for the money is not correct - not worth it
