Looking to possibly put some HFC's on my 13 FX37 and was wondering if anyone has installed some and what the consensus was on them. I previously had Berks on my G35. My FX is awd and was worried that the O2 sensor extension might get in the way of the driveshaft. Was looking at the Invidias but still like the fact that the Berks have the peice that's mounts to factory support.
