Racingline High Flow Air Filter – Audi RS6/RS7 (C8)
Let your Audi RS6 or RS7 C8 4.0 TFSI breathe more freely with the Racingline High Flow Panel Air Filter. This is a direct replacement for the restrictive factory paper filter, giving your twin-turbo V8 a simple, reusable upgrade that fits exactly like the original part.
The standard paper filter does its job, but it creates a noticeable restriction in the intake path. Racingline’s panel filter uses a triple-layer Trifoam® element that allows more air through to the turbos while still filtering effectively. The result is improved airflow, with small but genuine gains in throttle response, power and fuel economy.
Why upgrade the panel filter?
- Reduces intake restriction compared with the factory paper element
- Reusable lifetime filter, cleaned and re-oiled rather than thrown away
- Maintains OEM-level filtration to protect your engine
- Direct drop-in fitment, no modifications or remapping required
- Warranty-friendly upgrade that retains the factory airbox
Built to OEM standards
Hand-made in the UK, the filter is designed and built to the same standards as a factory part. The Trifoam® media uses three layers of progressively finer foam to trap dirt and dust effectively, while the outer frame is shaped to seal correctly inside the standard airbox. Fits like a factory part; lasts like a factory part.
Realistic expectations
This is a sensible bolt-on upgrade rather than a power-adding miracle. On a 4.0 TFSI V8 with twin turbos, the standard airbox is reasonably well designed, so the gains from the filter alone are modest. Where it really earns its place is as part of a wider intake or tuning package, and as a reusable, eco-friendlier alternative to repeatedly buying new paper filters over the life of the car.
Fitment
Designed specifically for the 4.0 TFSI V8 TT engine fitted to the Audi RS6 and RS7 (C8 platform). Please use the site’s vehicle lookup tool or check the Vehicle Fitment tab to confirm this filter is correct for your exact model and year.
Installation
Fitting is straightforward and takes only a few minutes. Open the airbox, remove the old paper filter, drop the Racingline filter into place and close the airbox. No tools beyond basic hand tools are needed, and no ECU changes are required.
