dont waste that money on the dealership the install only took ten minutes it is really easy, just drive your car till your rediculously low on gas then let it cool, put the front on stands,if you car is the early e36's the filter should be on the bottom behind the left wheel but under where your feet sit, under the car off course,remove the the allen bolt and the filter will now be able to move, disconnect the bottom clamp and put the little cap of the new filter on the old filter to stop excess leaking then put the bottom hose on the new filter then remove the top clamp on old filter, remove it, then put the top hose on the new filter then bolt the bracket back into place
remember dont smoke while doing this

just buy the filter from autozone as long as it is a fram or mahle
