TGK Motorsport Audi 4.0T Air Intake System - C7 S6/RS6/S7/RS7

At TGK Motorsport, we believe in pushing the boundaries of innovation, and the Audi 4.0T Air Intake System is no exception. It all starts with our meticulous flow tested design, developed from a 3D scan and transformed into a flawless 3D model. Countless design hours were dedicated to creating an intake system that delivers unrivaled performance.

The highlight of this system is the 4' Merged Inlet on the inlet side, allowing for easy installation by mounting to both turbos. No more hassle or complicated modifications—simply bolt on and experience the difference.

The TGK Motorsport Audi 4.0T Air Intake System is a complete package, including everything you need for a seamless installation. From the meticulously designed components to the comprehensive installation instructions, we've left no stone unturned in providing you with the best experience possible.

Flow Tested for Minimum Restriction & Max Velocity

We started by identifying the shortcomings of the factory intake system to determine which components restricted airflow to the turbos. We then focused on designing the inlet to function without restrictions by utilizing flow data.  We tailored the inlet design to accommodate the CFM required by the 4.0TT engine during Wide Open Throttle, and ultimately created in an intake that sounds and performs better than stock.

Louder Induction Noises! 

Per the design, both turboes are pulling through a single filter. In turn this creates extremely loud induction noises!
