I waited mine for 3 months also... Installation of turbo inlet, intake and cold air box with some cleaning (MAF, battery) was not exactly a "breeze"... took me hours and hours... my hands hurt... well nothing broken and works fine, I'm happy. Only wife does not know about this yet (sssh). I can recommend the cold air box (Corksport) if you find intake too loud. I may still be forced to add some noise insulation inside the box. That's the easy part.
One question, do I need to oil Cobb filter or is it pre-oiled? The instructions say "Enjoy your new intake", nothing about oiling. Just would like to be sure... no experience on oiled filters (sorry it may have been answered somewhere already (dunno))
