It's good air flow or good protection --pick one.

Keep in mind even a not-so-fine mesh restricts air flow significantly.
22x12x2,5mm wire mesh has a free area of 58%
6x3x0,8mm wire mesh has a free area of 47%
That means two things:
a] Your air flow will be decreased and a significant pressure drop occurs (0-5mm from where you attach it is another part of equation on top of laminary/turbulent flow change after the mesh)
b] The air will not get exchanged while stopped and that is the bigger issue since your auxiliary fans will have to run at full speed for couple of minutes after each run when you turn off the engine
Been there, done that

Ok, work is now starting on the new custom heat exchangers.
A few pics showing what was found on inspection. You will be surprised...
Stones are projected through the air vent in the inner wheel arch guards into the rear of the heat exchangers
The rear of the heat exchangers are more heavily damaged than the fronts

That's ridiculous. That has to be some paper thin aluminum. And then to have the audacity to push a ~$2,500 charge onto the customer to fix this. I'm having second thoughts about my car because of how common this problem is.

LMAO, this is unbelievable. I started up my car this morning and got a check coolant level warning. If I have a puncture I am going to be absolutely furious.

Most of the coolant warnings are just a few oz low as I have had 2 over the years and never see any leaks. Less than 6 oz in one of the tanks fixes it. sensors seem to be sensitive and oil warnings the same.

All of the issues people have had with punctures has definitely got me paranoid.

Perusing this thread when i noticed a leak out of my C63 that i suspected to be coolant.... and low and behold i have a pinpoint puncture on my radiator that is gonna cost me $2200 to get fixed.
Dealer is telling me to go through my insurance to get fixed (which... whatever)... but i'm worried that this will happen again. Anyone come up with definitive "fixes" for this? Anyone have any luck getting warranty to cover this?

I write in response to your recent email communication which was received at our office on the 20th August 2018.
It was with regret I learned of the issue with your Mercedes AMG GT R's radiator. From the information in your email we believe this issue to have been caused as a result of an external influence which means the repair will not be considered under our Manufacturer’s Warranty or goodwill, with this in mind we are declining your request for a refund for the repairs which you have recently had completed.
I do hope you can accept our apologies for any disappointment caused as a result of this decision.
Freundliche Grüße nach Berlin

I too too had a pin hole a excessive damage to all front facing heat exchangers.
I chose to to upgrade rather than have this happen again.
Give Dru from ARE Cooling a call.
