This got me thinking of something else to do with the vent

Hey thanks for the input! I know we talked about getting my rear diffuser tested out and I'm not joking.. I'm very serious about it
With this side vent piece I'm not looking for a drastic performance change.. I just want something that is not a faux piece that mimics a genuine side vent. I still do think however, even if it will be just a little bit, tunneling some air out from the engine bay could remove some heat. If it were to be super functional you probably need some sort of a naca duct to draw air in from the front of the engine bay (front bumper area) and guide it out through the side vent but my personal car is not a dedicated track car...
For example, canards and splitters do their job at the track and it's super functional but is it really a beautiful design? Hmm...
I would like a good compromise of both form and function, compromising more on the functional side a bit.
