A word to the wise. Adrain.b is pointing you in the right direction, however I brought a set of vents and grills of this guy and after only one month, the amount of paint that has come of is unreal. I don't know if I can prove it, but I believe that he has taken standard black grills and vents and then painted them himself. I will now have to strip down the grills and vents and repaint them myself. Hopefully doing a better job than him. The vents are not hard to take of, (just be careful not to snap the plactic retaining clips) and have a go at painting them yourself.
