Water spray underneath bonnet from road

[DaveMac]

Hi everyone hopefully can help so I noticed other day after it had been raining and I had be driving on the motorway for a while that when I opened my bonnet the next morning I could see water spray on the fuse box cover and a bit on the ECU cover plus a tiny bit on my induction kit filter on the right hand side, has anyone else ever had this issue just bit worried with it going on the filter if it gets sucked into the intake, car is a seat Leon cupra ST
Thanks in advance everyone
