It meets all criteria.

It's ugly.
It's expensive.
It doesn't work.

C8 drivers will love it.

It seems like $1200 for something the car does not need. Where it feeds into is meant to be a place where heat exhausts. This will likely screw up the engineered flow. I trust the GM engineers more.


If someone wants it for looks? Their money, their car.

It would be nice if they posted some proven results, if they are making claims. $1200 is definitely steep.

I like them, but wouldn’t get them. This made me realize that I have no idea where the C8 gets its fresh air for the engine from.

The side scoops have tubes that run to the air filter housing.

Those vents are to remove heat for engine compartment and have nothing to do with intake. ACS Composites makes great products but this one is a bust. The only thing it will do is bring more water into engine compartment when it rains causing more cleanup. Big Pass

I would like to get it and make it a fresh air intake for the air box.

Going to spend $1200.00 somewhere else that will make a difference 🙂

I love how the dude in the video just keeps saying words but none of it makes sense. It's an intake but also an exhaust vent. It's all the things.

Wonder if something goes wrong with the engine, if GM can deny warranty claim based on this mod....

Why would the air be fresher or colder there rather than the side vent it already draws its air from? Have you checked your IATs versus ambient? Would it be cheaper to insulate the air box and intake tubes and get better results.

No science comment from me.
Originally these OEM vents expel heat, not so sure they draw in air.
The OEM vent fully functions at a standstill, yet as heat rises, some hot air may be expelled at speed, with an assumption aero-wise air flows over (not in or out) the vents at speed.
With the add-on scoops, air is forced into the engine compartment, thereby bringing a cooling effect at speed.
But, does this induced air become trapped, increasing lift, and where does the air exit the engine bay?
If the induced air design exits through the rear bumper vents that may be okay, yet if exits to the undercarriage, I could only guess the effects on the rear diffuser and floor.
So....I don't know what I think, however, I do like the design and appearance.

I went and watched the video link. My only concern is it is putting air in where it was designed to let hot air out.
