Yeah, I have had it in for 4 days and I have no problem with it, and I suppose if any of the other 335I Coupe owners had issues it would have come up by now through someone, its just odd that it is recommended for the 328i E92 but not the 335i E92. Digging through BMWUSA accessories, the SSK Kit is listed under the 2008 E92 328i but not the E92 335i, just odd only time will tell.
