Intercooler...
Is that true? No front mount Intercooler like the 335i?
The S55 uses air to liquid intercoolers, the aluminum boxes by the engine transfer heat to the liquid but there has to be another heat exchanger somewhere to transfer heat from that water to the air. That's probably mounted in the front like the FMIC on a 335i.

Using a liquid cooling system with the air to water heat exchangers so close to the turbos and engine should be great for throttle response, the charge air won't have to go through an entire frount mount intercooler like it does on the N55.
