I have used Vette C7 rear oil coolers inlets... they are not a perfect fit due to a different radius/bend of e92 hood however they work well and could be made fit perfectly once you don´t mind to mod them... that what I will do once respraying the hood/bumper eventually... so far I take it as a functional thing :-)
And it really works, you can see the heat coming from them when stuck in a stop/go traffic or even moving slowly... while driving in the rain you see a dry path on the hood too...
