This might be a stupid question, but where does the air filter go?
Does it use the same air filter as the E46 M3 CSL?
I wonder just how much of the claimed 25-30hp gain would you say is coming from getting a remap and how much is coming from the carbon airbox design?
The Evolve website claims 15-24hp gain alone for just the remap

And for only $799, it might be an excellent deal!
I know the sound of this carbon airbox is awesome. However, the cost is way way out of my price range.
