My understanding is that for every 2% rise in ambient Temperature , an Engine losses 1 H.P.
Jaguar did the same thing with their E Types with the Air cleaner on the side of the Engine drawing cool Air.
Both our modern cars a C Class and a Mk V11 Golf have cold air intakes , std.
In that case why don't manufacturers draw in cold air from the air-conditioning unit? They already use the air-conditioning to cool fuel lines in some models ......
Maybe it's not necessary but it's a question to ask.
