These cars also have the PPK(extra radiator in the passenger fender, higher wattage radiator fan, sound generator and SW tune from BMW) already installed along with a different flywheel and clutch - which the normal x35i cars did not get.
The 335is/Z4is/1M cars do have a special SW tune that also allows for over boost in the low to mid range for short periods.

I have the extra radiator in the fender of my factory 2007 335i coupe E92 (w/ N54 (2-turbos)) with sport package ~Frost
