This cold air intake is manufactured from a high-quality rotomold procedure that produces a
superior plastic material with consistent wall thickness, strong corners, and excellent heat
resistance. Enjoy a proper motorsport-designed intake system without compromise.

The internal volume of the intake and its complex shapes are the results of application-specific
engineering for the Audi B9 platform. Every inch has been performance designed to feed your
turbocharger with the most airflow possible.

The integrated velocity stack smooths the airflow from the large filter into the charge system with
excellent laminar properties. This powerful design detail results in a very high inertia flow with
reduced drag and power-robbing turbulence at the critical point as air enters the turbocharger.

This intake features high and low pressure zones to feed the turbocharger and engine demands
for any power goal. The majority of fresh air supply is supplied to the filter from the grill. If
additional air demands are required, the intake will pull low-pressure air through the filter cover
as needed.

The stock airbox on your Audi A4 or A5 2.0T has been manufactured to silence all engine and
turbo sounds at any performance cost. Upgrading your air system with an IE polymer intake will
release a symphony of engine throttle, spool, and blow-off sounds that will be music to your

Countless design revisions, rapid prototyping, flow bench testing, dyno runs, and real-world
verification has resulted in a performance intake design with power gains of up to 10-20HP on
tuned engines!

Back-to-back flow bench testing details consistent airflow gains of up to +70 CFM over stock!
This increase shows efficiency over the factory parts and capability to provide increased airflow
demands from ECU tunes and performance hardware upgrades.

Install your new air intake with basic hand tools in only minutes. Our polymer intake is a direct
factory upgrade with stock-style mounts for a perfect, hassle-free installation.
