up to 18% cooler engine >100km/h

not sure about the colors and finishing yet, I'll probably go for hood repaint, all green and black grill only... or also green

This is not just a guess, it has been designed and calculated by a engineer friend
the position is very precise
these type of extractors work like compressor vacuum tools
from 100km/h the airflow on the hood starts sucking out the hot air right before it goes to the engine

still working on the final version
Finally I found it not good to apply those agressive late shapes from black series on the W215
So after 4 days designing I found the final version
here is progress
final paint tomorrow, All original green and black grill

Crazy to cut into the stock hood like that but it actually looks quite good. No issues with rain getting on anything important if it's parked outside?

I will install a rain rail inside of course for the rain but so far it rained really hard 1 day and had no issues

btw, with 26°c outside, engine goes to 82°c max when driving at 90kmh

oh forgot to mention, I have a 2001 CL600 donor, just in case...

Final stage
after multiple tests I finally chose OEM green paint everything and removed the stupid MB emblem as there is a huge star just below
chose custom black grille for the extractors you'll see when mounted
Did some extra DAS programming and now get 81 celcius / 177.8 Farenheit engine temp with normal driving from 100 kmph / 62 MPH (this is the minimum speed for the extractors to be 100% active)
ths with a outside temp of 30 celcius / 86 Farenheit
my extractors are 30% bigger then the black series version
used 3x original MB bi-comp HS varnish

OEM covering did sound & heat but too thick and heat retaining

I use titan-aluminum 6 mm sheet glued with Special Pattex for high temperatures Neoprene based glue

not completely finished around the heat extractors yet
