Intake Conversion | Audi - C7 S6/RS6/S7/RS7 (Stock Airbox to 4" Filter Conversion) | TGK Motorsport

Overview

The factory intake system on 2012-2018 Audi C7/C7.5 S6/S7/RS6/RS7 4.0T platforms creates restrictive airflow with undersized tubing that chokes your twin-turbo V8's breathing capacity. The stock 3" diameter limits maximum CFM throughput and muffles the aggressive turbo induction sounds these engines are capable of producing.

TGK Motorsport's 4" conversion intake system eliminates these bottlenecks with precision-machined billet aluminum construction and premium silicone couplers. The larger 4" diameter increases airflow capacity by 33% while amplifying turbo spool and diverter valve acoustics for that signature forced-induction sound.
