S3 Airfilter


Registered User
Looking past the ' English Summer' and onto the wet winter period does anyone advise changing or doing anything to the air filter? I have a 67 s3 s tronic petrol which has only done 21k. Anyone came across any air filter problems?

Coming from a Ford Focus Petrol Hence my worrying.

No problems at all with the OEM filter and it was still pretty clean after 30.000km.

If you want more induction sound you could change it to a Pipercross panel filter (and also modify the OEM intake: https://www.audi-sport.net/xf/threads/modified-oem-intake-8v-s3.266915/).

Performance wise there is very little difference if any but the "woooosh" is more pronounced.

I replaced mine with a pipercross panel filter. feels a bit more responsive although the filter which came out looks pretty dirty so that might be why.
