So i installed a pipercross cone filter. Car has a nice engine sound and has good torque. But between 1300 and 3000 revs The car makes inside a loud air sucking noise going through The turbo ik guess. Cant describe The sound accurate in english. When accelarating 100% is less noticable. The sound is only under load When driving. Anders stops at 3000revs.
Connections are ok imo. Can annyone confirm if this is normal?

This is completely normal mate

thanks mate,

oil in filterhousing also normal? car doenst take any oil but i saw the paper filter was a bit oiled and also the airhose.

Yes, that je normal. Some oil gets from oil vapour catch box in intake
