Just ask year leasing company.
I have installed a roof spoiler and lowering springs on my previous car and the leasing company had no problems with it, but they would not allow installing a K&N air filter.
My E90 is leased through the dealership. I am planning to mount the Hartge front lip and my salesman has no problems with this. Maybe he would if I would "rice" my car with some kind of horrendous front bumper.
