BMC Airbox

Hi, guys! Have a question about the BMC-Airbox. What I have found out so far is the right one for the 180er the CDA SP 05 (with direct connection for LMM). Has someone installed it? On pictures the connection looks very short, so that the LMM stands in the box extremely far – then there is only a small gap to suck in, since the filter sits cylindrical in the middle of the box. What do you say about it? Information about the filter e.g. at www.bmcairfilters.de
