Similar to mine, changed them to a pair of K and Ns, cheaper than a pair of OE..ImageImageImageImageImage

No, B9 only has one.
It’s round, not a panel this time.
My B8 was just like stuartbarriskell, which prompted me to have a look. I think the Audi schedule first looks to replace the air filter at 60,000 mls!

Forgot I had posted those images up a while back.. I'm losing it...

One is better than two, I guess, I usually go OE on filtration, whether it's car or bikes, considering the price of a pair of OE a quick scout about and the K and Ns were a favourable option..


You'll be glad you checked. it looks worse than my two...
