A1 Sports Line 1.4 TFSI Upgrades (2015)

[elrasho]

Hi,

Had my car for about a year and a half and looking to upgrade it.

First thing I plan to do it get H&R 35mm lowing springs as I feel the height is far too high

Is there anything I can do about performance? Do aftermarket air filters make that much of a difference?

Thanks
