The "which intake best" debate has been beaten to a pulp. Terry@BMS collected an abundance of data that showed there was no significant difference of IATs between open vs. closed filters.
If you want something aesthetically pleasing, yes the Gruppe M or Simota are both CF and look nice. But if looks don't matter (and they shouldn't be the #1 factor when buying an intake since you drive with the hood down), then the BMS DCI, aFe DCI or Injen DCI are all perfect intakes that will all give you better "bang for buck" then the Dinan or any other pricey intake.
And you should be cleaning your filters every 20-25k anyhow. Even the filters in a closed element intake is going to get clogged from filtering out leaves/crap that tries to enter the intake tract.
