Intake system
The vacuum system has been adjusted to the installation situation in the F10 and receives a flow-optimized connection to the throttle body at the same time. In contrast to the engine S63 the engine S63 TOP does not have a blow-off valve. The engine S63 TOP has its own intake silencer for each bank. One hot film air mass meter each is installed in the intake silencer. The use of the 7th generation hot film air mass meter is new. The hot film air mass meters are common parts from the engine N20.
The air-coolant heat exchangers have also been adjusted to increase the cooling power.
The following illustration shows the components that are involved in the through-flow.
