I own an Audi A3 S line 8V (facelift). There is a box underneath the passenger seat with vents on either side and on the front. I was wondering if anyone knows what it is. I do have the optional Harmon Kardon sound system, maybe it's something to do with that? If anyone has the answer could you let me know. Thank You in advance

Hello Gareth, Thanks for taking the time to not only reply to my post but also giving me a real world view and also giving me lots of things to think about before I decide to make such a choice. I have a 2016 facelift Audi A3 s line, and they came with 18 inch alloys from new. I'm not sure about the exact tyre dimensions as I haven't had to change the tyres yet in my ownership and I'm not near my car at the moment. There are two reasons I wanted to upgrade to 19's firstly I wanted a more sporty feel while driving, secondly, they'd look so cool and lastly, the alloys I was thinking about buying only come in 19's however, I'm not sure if it's worth getting a bigger alloy hence why I'm after some opinions and ideally some advice from people who have done it. Thank You, Habib

May I ask, how you've found your 19 inch alloys on the A3. I'm looking to upgrade mine to a set of 19inch alloys but want to know if I'm going to be giving up too much in terms of comfortability and fuel economy to achieve it. Thank You

Kormoron Tyres are really good value for me. So I've heard.
