Picked up a g37 a couple years ago looking to start adding some aftermarket parts Looking for a good deal on a cold air intake . Also looking for a used cat back for a 2012 awd sedan . I have hks axel back now . I have an alpine pdx v9 all new guts from alpine never used and a new lc9 lineout converter if anyone wants to barter with cash . I was going to bypass the bose with it but decided to do performance over audio .
