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.

How much louder will my turbo sounds be?
The 4" conversion significantly amplifies turbo spool and diverter valve sounds compared to the muffled factory intake, giving you authentic forced-induction acoustics without being obnoxiously loud.
Do I need a tune after installing this intake?
While not strictly required, a custom tune is recommended to fully capitalize on the increased airflow capacity and optimize performance gains from the 4" conversion system.
What's the installation difficulty level?
This is a direct bolt-on replacement using factory mounting points. Most enthusiasts can complete installation in 2-3 hours with basic hand tools and no permanent modifications required.
How often does the cotton filter need cleaning?
The multi-layer pleated cotton filter should be cleaned and re-oiled every 15,000-20,000 miles depending on driving conditions, or annually for optimal filtration and airflow performance.
