Will a air filter cone just connect under the bonnet or would you need the whole intake kit to go with?
Will likely need to remove the airbox to give it room to sit and probably an adaptor/silicon hose to connect it to the intake mate.
Just read that yours is a 2.0 tdi. No real benefit of a cone filter on that to be honest with you. There is another thread similar here. http://www.audi-sport.net/xf/threads/cone-filter-on-a-2-0tdi.337219/
