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 ALUMINIUM

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 sold separately. Here is the link:
