Which after-market filter?
Having just bought my Allroad and seeing it's due for a service, the air-filter is right up on my list of things to do. I tend to keep cars for a long time, so a cleanable air-filter appeals to me as it's cheaper in the long run and requires less maintenance (most flow better even when part-clogged than a paper element can manage).
My options then are: K&N (cotton gauze); Pipercross (foam); ITG (triple-density foam - if they do one). I've used ITG before on a 4x4 racer and it was fantastic, so it'll be my preference if they make a replacement panel element, but it's not shown in their catalogue.
Does anybody here have any experience of these filters and is able to offer any advice?
