If the A/C vents in your BMW Z4 hot rod are broken, you've come to the right place. Unfortunately, BMW dealerships charge $150-200 to replace a single vent, but there's now an affordable , better DIY solution . Instead of replacing the entire vent, how about just replacing the Venttab? It's simpler, much cheaper, and doesn't require any tools.
These particular tabs are designed to fit the front middle and side vents of a BMW Z4 (E85) 2002-2004.
To install, just locate the vertical post behind the louvers of the vent and slide the tab into place.
The patent pending , one-piece Vent//Tabs design allows you to install it without removal of the vent or the vent louvers (fins). To install, just locate the vertical post behind the louvers of the vent and slide the tab into place. https://www.youtube.com/watch?v=Ua8Avokann4 Check out this video : The Vent//Tabs Advantage
