That's the ultimate goal but its still a VERY fuzzy picture when it comes to removal/replacement of the factory hydrocarbon filters. CARB does not have a test for them yet so no intake that gets rid of them will be able to be CARB approved. We have integrated a carbon liner as our own solution to replace what the hydrocarbon inserts did (have used this method since the F10 M5 intake on affected platforms) and that is in the process of potentially being a approved solution. However, it all comes down to what CARB does for a test that currently does not exist.

Do you have any plans to also develop new lower filter boxes and intake pipes with scoops? Or are the stock ones good enough?
No plans to. There is no gain in real estate (volume) by replacing the lower boxes so it would just be adding cost unless you somehow integrated a secondary air inlet on the bottom but thats what the top scoop is for so to do both is a bit overzealous. Truth is the stock intake/configuration flows enough air to support up to stage 1 power levels. The main purpose of the intake is the optimization of that flow and getting the pressure as close to ambient as possible to reduce workload on the turbos for a more efficient system. Now if you are planning on building a 1000+ HP monster, then yes, the intake does flow more to support those numbers. However, the vast majority of folks that will make no difference for.
