Thanks for the responses guys. I looked around and found that the original ones are from Valeo's SWF series (800), which are available. I have PIAA (silicone) on my Jetta, and they've performed well for a year now, but they are pricey. The PIAA also come with an optional spoiler too for the X5.

So, now I've narrowed it down to the PIAA with the spoiler, the Bosh Icon's or the Valeo SWF 800 (OEM) for the front. For the rear I think I'll go with Trico as I read here it's a perfect fit. If anyone else has experience with the above, please share.
