Welcome to Dr. Björn's Auto!
Well take a breath, take it easy. Once in a while you may let the engine cool too, especially after summertime hill climbs, while you look around and create a bit of awareness beyond the road. The air is there for you to enjoy and of course help maintain for all of us too.
It's free (and we have to take care of it).
P.S. Make sure that the engine compartment seal is intact as it helps to avoid the intake of hot air.
