carbonio airbox didnt make any power :(
unluckily the car did not change in power with both the box's.
276.6rkw peak for both (stock and with carbonio).
Another amg did get 301kw stock but my throttle opening was at 50% the whole way but his car was at 80%...(he had the row airboxs with stock filters)
Quite disappointed, also my heat shield from the exhaust headers was missing for one side as the previous owner may have tinkered with the car.
BUT, with a dyno tune due to the 12% bigger volume I may be able to get 2-5hp more at the wheels..

But one thing this post has done for future buyers of carbonio to not trust the fake power gains etc.
Bigger inlets would yes give more air intake but unless the inlets are changed on an e63 it wont matter.
I know for the c63 there are bigger air inlets out there which do work.
Not quite sure why anyone hasn't designed this for the e63.
Srsly. I don't get it.
The product is know to have a finish that fails. And now documented zero power gains.
That's a bad product. It's not as if the vendor is giving these things away. Hold their feet to the fire, and get your dosh back. No reason to play ben dover.








100% correct, also with these cars each motor is the same but different at the same time.
Some e63 6.3s come with 300kw at the wheels, some come with 276, some with more or less.
Each hand built and slightly different.
I've come to know this fact as when the guy showed 4 different e63s lined up stock from on a dyno they produced all different amounts of power.
Now in saying that if you go with renntech or any other company they will give you a generic tune which may or may not give your cars many gains or how it will affect the motor in the long run.
My whole idea of modifying this car changed when I found these little things out, so Im going with a custom dyno tune.
