I'm selling my Power Labs 3/8"plenum spacer which was installed on my 2005 350z DE. It is in very good condition and works fine. I do not have the installation hardware for it as it got reused on my new Motordyne plenum spacer. You can pick up replacement hardware (bolts) from z1 for $20-25. I am located in NJ if interested in local pickup, or I can ship. Asking for $85 plus shipping.
