A4 2.0 tdi air filter

Hello folks, first post, has anyone bought the upgraded k&n type air filter and saw a difference? 97 quid seems steep to not get any real life gains from it.

You'll get minimum gains tbh. But it's a filter with a life time warranty (,or used to be). You'd only see a benefit if you added a cat back sports exhaust abd remap to be honest. Bare in mind it would be classed as a mod too so insurance would need to be notified.
