I've considered using the brake duct cutouts on my front bumper to allow additional direct cooler air flow to the filter..
So far no overheating issues on my setup.

I got a 1.5" to 2" coupler to put on the end of the BOV, then a 2" to 2" coupler joint, then a 2" to 2.5" 180 degree elbow. then got a 2" ID PVC pipe approx 9" long, that goes inside the end of the 180degree elbow, capped the end of it. Drilled about 120 or so 1/4 holes in it (none aiming down at the IC), Got some 3" length x 2.6" OD with a 0.8" OD internal hole aquarium sponge filter that I stuffed inside the pvc pipe and then ran some zip ties through to keep them in place. and then I placed a 6.5" KN cone filter over the exposed end of the PVC to clean up the appearance and keep debris/water etc... off of it.
Now I honestly forget it even has a BOV. Probably 80% quieter vs without. Before it was so noisy and annoying in typical city driving, sounded like a jet 24/7.
I got some pictures up on the G forums someplace.
