Side fender vents real???

so I learned a lesson many years ago when I built and flew model airplanes. An exhaust for heat if it is to be effective, needs to be 3x the size of the inlet to allow for expansion. I really doubt those slits do anything measurable. I could be wrong, but I'd be really surprised if there were any change in underhood temp if you blocked off the slits.

Hate to be the bringer of bad news but it is purely cosmetic and non functional.. Check out this vid and go to 3:45.. I wished it was otherwise.. don't shoot the messenger

Straight from the website... (Thanks to av8or)
"Functional side vents expel heat and equalize pressure around vehicle at high speeds."
I think we can finally close the hatchet on this topic, lol.

Does that mean my C-west side skirts exert even more down force!?

To my surprise, the IS250/IS350 utilizes the same two holes on each corner of the engine bay to expel heat (Small rectangular cutout on top and a larger oval hole slightly below [it was difficult to photograph both holes in one shot but the red circle illustrates its location]):
From what I could see with my flashlight, the heat from the ISX50 would then exit through the fender compartment in what appears to be the same design as the 3rd IS-F picture you posted. The green arrows that I doodled up match the three holes of the picture you provided:
So are we back to debating on whether or not the side fender vents are real since the ISX50 utilizes the same/similar design?

Yeah, there's definitely no visible side fender vents on the ISX50. I'm just pointing out that all three 2IS models utilize the same ports to expel heat from the engine bay through the fender compartment. I think the question then would be whether or not hot air dispels through the IS-F's side fender vents (which would make them functional).
