Side fender vents real???

The holes aren't fake, they're holes, but does the slit actually move air from the engine bay to the outside? Seriously doubt it. There's no hole in the engine bay leading to the vents. Air is funny and it only moves from regions of high pressure to low pressure. The only way to be sure it to test it, and my bet is you won't see any significant air movement when you do.

In the RCF press kit it has a picture showing it removing (Hot air?). I don't know if the RCF's vents were made to be more function vs. the ISF. Honestly if they do anything it probably has to do with a slight change in aerodynamics. They probably are mostly for looks to lessen the transitional impact of the wider fenders and maybe they give a little functional side benefit.

I wanted to believe they were functional.
Maybe the aftermarket can come up with a product. I'd buy it, as I'm limiting myself to making only functional mods to the car, & adding nothing cosmetic. I did break that rule though with the Toms diffuser installed this week (price was too good to pass up).

The air blasting into the egine bay finds its way out of those vents when the car is moving..
Of Course they are Functional..!!!
Just dig up some photos of the IS F with Fenders removed and you'll see the holes that route from the engine bay..

Pulled from a different thread, but why is it blocked off with a plastic piece when you look at from the side of the car?

So, I repeat what I said, there are no openings in the engine bay leading to the front fenders. None. If those vents vent anything it is air trapped behind the fender, not heat from the engine bay or the brakes.
From TIS New Car Features where all things like this are described in detail:
IS F - The voluminous hood and side outlets create the distinctive “F” form.
RC F - The "F" shaped side air vents that extend to the top of the front fender not only give a dynamic impression but also aerodynamically enhance handling stability.
Shapes provided in front of and behind the rear wheels realize both excellent aerodynamics and a wide and low stance.
So there is the reality. The F's slits are purely for styling, and the RC F's are functional.

From the TIS New Car Feature description, it didn't directly say the side outlets were non functional right? Here's hoping they serve some kind of purpose instead of just a styling cue.

Lobuxracer, if they are just for styling do you know why they have the 3 actual holes cut out behind? Could it be some kinda of "chamber" that draws heat out from the top two smaller holes and exits the bottom larger lower one? You would figure with Lexus/Toyota if they were not functional at all, why go through the trouble of making the 3 "vent" holes, just stamp it a solid piece right?
