Pencilgeek tried one of these and got some decent results. If you search the forum you will probably find that thread.

You can PM me if you are too embarrassed to admit you tried one of these systems in public. I am seriously thinking about taking the eBay plunge on one of these carbon intakes, which are listed as a "Gruppe-M Style" systems.
Have you, or do you know someone who has tried one of these systems? What's the sound like? Any CEL issues?
