Just installed this today, took maybe 45 minutes, 15 of which were spent tracking down a deep 10mm socket that an offspring-that-shall-remain-unnamed didn't put back on the rack. Installation was flawless, everything lines up perfectly and there were no missing parts.

A bit louder at full throttle than the stock airbox, feels stronger, but have not yet done a comparison of 0-60 mph and 40-60 roll-on times. Will post results when done.
