If you get one I am sure you will be happy; BUT, if you ever are inside a an m3 with a proper carbon airbox or hear it in person at all, you will wish you went that bit further.

In my opinion , buy the airbox.

There are ones from germany that dont look as good but are very functional and sound incredible. 1100 or 1k delivered. They are all about function and wont be as nice looking as a eventuri or karbonius.
