It seems most people are using the bosch aerotwin. I am using those too, however my new ones are a little different. I used to have OEM ones from the dealer, which means bosch just without the logo and got the new ones in October, online for about 30€.
The spoiler design is different in these even though i'm convinced they are genuine. In the old ones the spoiler was offset towards the back (upper side) so as to be more aerodynamic. In the new ones, the spoiler is right in the center and less rounded/more angular than the previous ones. The clip is also different, those are called multi-clips. I like them less because the clip is a little bulkier comparing to the previous ones in order to accommodate more connectors. Its funny i even noticed it but i did, and then it started bothering me, lol. Wondering if anyone else has had the same experience.
