AWE Tuning S-FLO Engine Air Filter Overview
Upgrade the way your Audi breathes with the AWE Tuning S-FLO Engine Air Filter, a direct factory replacement engineered in-house at AWE to slot straight into your existing air box. Designed for the Audi Hatchback/Sedan platform with 2.9 and 4.0 AWD powertrains, this washable, dry-element air filter uses the proprietary AWE S-FLO Filter technology to deliver more airflow than the restrictive stock element it replaces. If you have been searching for a serious engine air filter replacement that mounts in the OE location without guesswork, this is a purpose-built solution.
Unlike a disposable paper car air filter, the S-FLO is built from cotton and finished in a distinctive yellow, giving you a reusable filter that can be cleaned and re-installed rather than thrown away at every service interval. It is the largest filter that can fit within the factory air box, maximizing surface area while retaining a true OE fit. Because it is a genuine direct replacement, no tune is required and installation is straightforward using the included hardware.
