If the air filter were charcoal I might let it do its thing, but when you get behind the occasionaly oil buring car/truck or what ever I liek to keep those odors out and by the time you realize it and switch it yourself it is too late. I always used to leave it open on previous cars, but my last 2 I leave it closed as much as possible.
