I want to give information to all users who purchased the filter BMC-CDA: leaders of BMC told me that, if they sell many kits could also think about making the connection pipe between the throttle valve and the filter,in carbon! Therefore, if you buy the filter, ALWAYS ASK IF THEY EVEN THE CARBON TUBE! the greater the demands and more likely is that they do!

 

here you can see my car with BMC CDA airbox:
