On E90, 4-porter, the air intake system showing 2 channels.
For those who had install air-scoop will realize that only 1 channel is opened and the other one completely sealed. On the 6 porter, both air-channels are opened.
Has anyone tried to open the sealed-channel making both channels opened to maximize colder air intake? Otherwise, only 1 scoop is effective the other one just cosmetic only.
Any one can share their experience?
