The mesh is approximately 55mm thick (S2: 35mm, RS2: 44mm!) and fits the original mounting points. The fan shroud/air conditioning cooler can also be easily installed. If a motorsport intake manifold requires a version without a connection for an auxiliary water cooler, see: https://shop.5-inline.de/teil-188.html
The optional radiator fan switch comes as a motorsport variant to limit / regulate the thermal loads and associated wear by switching on the fan earlier:
Motorsport switch: 1st switching stage - 87°C - 77°C; 2nd switching stage - 92°C - 82°C
