Couldn't find anything about this using search so thought I'd ask...

Is the North American G30 M550i factory equipped with a secondary charcoal filter in the air intake? (not the charcoal cabin air filters). Other BMW models have it in North America for emission purposes to limit vapors from coming out of the car when it is turned off.

Charcoal intake air filter delete is a common mod to supposedly, slightly improve throttle response.

Thanks...
