why no brO? is it ugly to install on FLX? need some advise...

waktakfak, just went out UOTT with davidke and some TCSS, back already few pages..
you guy really active man.. 

installed cabin filter by davidke, then having lunch with him, take some tour tutorial about vacuum reading in his car, jam here and there, luckily manage to find some route which able to test the vacuum reading in higher speed...

learning new driving style using vacuum gauge, and this is new guideline for me to challenge my next FC 

got back at puchong tesco, got back to my car, start engine, turn on aircond and.... weeeeeee......    need some time to adopt this new feeling 

Those who have "wheeeeee" sound issue with your cabin filter, please arrange a TT for me to troubleshoot. So far I installed several car no such issue. Not sure whether you installed correctly.

I myself got no such issue unless I'm on 4 speed, otherwise no problem. Paper filter is very efficient in filtering micro dust. Therfore some wind resistance noise is expected. Rest assured, wind flow blockage is minimal or NIL until dust clogging the filter.
