My X5 just came off warranty with the free maintainence a couple months ago, so I have now changed the windshield wipers myself for the first time. I took the advice of many here, and installed Bosch Icons. My question is regarding the "wing" on the driver's side OEM wiper. It obviously won't go on the new Bosch wipers. Is this a problem? Does the Bosch just not need it?
