Interesting...I remember when they started carrying Karbonius it was a big thing (they were much more expensive, but ordering within N. America with no lead time is a plus).

These seem to have a unique unfiltered section that works without a separate snorkel. This should be a plus for us Z4M guys as the CSL snorkel doesn't fit without major modifications and running without one (like I'm doing) looks unfinished.

It doesn't seem as polished as other offerings like Karbonius or Streamline (QA issues I'm experiencing aside). Right away I notice the weave from the two halves don't line up at all on the gloss version. Although they seem okay on the matte version so maybe it's a pre-production of sorts?

Having been through this I'd personally just go for the tried and true Karbonius offering which is (after shipping) around the same price as this and experts comment that current Karb offerings are as good or perhaps better than OE CSL intakes from Die Wethje.
