Overview
The factory airbox on 2012-2018 Audi C7 S6, RS6, S7, and RS7 models restricts airflow with its complex dual-inlet design and plastic construction. The OEM components create turbulence and limit the aggressive induction sound these 4.0T twin-turbo engines deserve.
TGK's cast aluminum intake system eliminates these restrictions with a single inlet design that's been flow tested for maximum velocity. The result is improved throttle response, louder turbo induction noises, and optimized airflow to your Audi's high-performance engine.

Frequently Asked Questions
Will this intake fit my 2015 Audi S7 with the 4.0T engine?
Yes, this intake system is designed specifically for 2012-2018 Audi C7 platform vehicles including S6, S7, RS6, and RS7 models equipped with the 4.0T twin-turbo V8 engine.
What's the difference between the 4" and 5" filter options?
The 5" filter provides 25% more surface area for maximum airflow and extends service intervals. Choose 4" for daily driving or 5" for track use and maximum performance applications.
How much louder will the turbo sound be compared to stock?
Expect significantly more aggressive induction noise with prominent turbo spool sounds. The cast aluminum construction and single inlet design amplify the natural acoustics of your 4.0T engine.
Does this require any ECU tuning or cause check engine lights?
No tuning required for installation. The system maintains proper MAP sensor integration to prevent check engine lights while optimizing airflow for both stock and tuned applications.
What OEM part numbers does this replace?
This system replaces OEM part numbers 079129572N and 079129571P, providing a complete upgrade over the factory dual-inlet airbox assembly with superior flow characteristics.
