Lund's version is not out yet. I'm hoping that Lund will produce Hood/Bug deflectors.

I am still waiting for mine from Weathertech. These are made in Germany. Tied up with Canadian authorities :D

Here's the link to weathertech:

Lund International have released the Bugflector II (P/N 24648) and the inchannel Ventvisors 4 piece set (P/N 194527).
