I found this picture in the net. Is anyone here who knows about this solution, or even has created it? If so, does it work properly? I currently make some research which way to go for a good working cold air intake for my Sigma 4/4 which is efficient, not too loud and at reasonable costs.
Regarding the picture the "half" of an airbox could protect against too much noise, the filter seems to get cold air via the side louvres. I'm wondering if the airflow is sufficient.
