Doesn't the N54 have relatively small turbos? I don't know off-hand how much boost is produced stock, but it would seem an aftermarket BOV would be more a matter of asthetics than need.

quoted from GFB:

"This system means that about 50% of the air is recirculated.... also means that certain Audi/VW, Nissan, Mitsubishi and other cars with sensitive airflow meters can use this valve."

Yes, they arent high capacity turbos by any means. Im sure there will be plumbing and coupler upgrades in the future of they arent already out now.

Dont these cars run two small Air to air intercoolers, opposed to one big front mount?
