Don't the GS/Z06 have something similar from GM?
I'm guessing that the GM version might be more effective, but that's just speculation.
Yep, and no speculation. Below is a pic of the vents on my 2017 Grand Sport. I'm sure with wind tunnel tests GM has optimized air flow to the dif and trans air/fluid coolers behind my fenders!
The factory scoops flow with the design of the car better than these aftermarket units. I bet the aftermarket ones pull in more air and at the same time create more drag due to their closed off sides design.
Are the scoops for show on the base stingray or do they actually have duct and air flow to the heat exchangers. I know they are functional on the GS and Z but thought i read where that is not the case on the base stingray, could be wrong. Seems if they were functional they would have the scoop like the GS and Z.
These are not functional on the Stingray and to make them functional so that air flows to the transaxle etc, will require some modifications that do not sound simple. such as taking off the fenders.

FWIW, the base C7 automatic has a functional left vent that goes through a duct to the air/fluid heat exchanger behind the fender. The right is non functional.
An M7 base C7 has neither functional, do ducts no heat exchanges.
Opening the blocking plate would be less than useless! No plastic ducts going to heat exchanges, just MORE drag!
The manual differential fluid cooling operation is interesting. The Z51, GS, Z06 have a small oil pump on the pinion shaft that circulated the fluid though the air/fluid heat exchanger behind he fender ONLY when the car is moving. My C6 Z51 standard shift trans had a similar oil pump that only operates when the car is moving BUT it's cooling was more complex!
First the c6 transmission was cooled like an automatic with lines going to the front radiator. BUT rather than that cooled trans fluid going straight back to the transmission, it went through a fluid/fluid heat changer much like the engine oil/engine coolant heat exchanger on a dry sump C7 (near the filter.)
Differential oil pump on end or pinon shaft Cooled returning trans fluid goes through fluid/fluid heat exchanger cooling dif!
Put me in the camp for preferring the "scoops" on the GS/Z06 over those aftermarket units. They don't appear to flow well with the angular design of the car. I have a Z51 car, so mine are functional, but if I ever felt a need for a bit better cooling, I'd get a set of the GS/Z06 OEM scoops, install those and call it a day.
when I bought my 2014 Z51 vert used I found a set of these in the trunk but had no idea of what they were for or where they went. Looks like you would have to cut a hole in each fender to install them.... somehow I don't think this is a good idea. CJ

Where did you get those little black decals? I've been looking for some like that for a while now.

Anyone install vent enhancers?
