kyusuke, that hose.. is the "breather" for ur engine cover, it sucks air in from ur filtered air box( with air filter of course) and goes into the cover, some kinda cooling/cleaning effect in ur engine cover there... most that change open pod will throw that hose away.. and buy small brether plug in....
ur car.. kasi buat sikit sikit..POWER! can beat my slow slow proton.. hahaha
jvolt.. RM 10 for 30KM! thats BAD! lol mine goes for 50 Km already wanna cry.. hahaha anyway.. you can check rather is ur carburator tuning correct or not, or perhaps driving habbits, there are alot of possibilities that cause fc increase both base on human / mechanical factor.. you can check few things to see got spoil or need to change.
carburator tuning
air filter
spark plug / cable / distributor
engine oil ,etc
exhaust syustem * check got leak or pecah somewhere or not
timing belts those.. *like my firends aircond compressor kaput.. make his enging lost power thus increase his fc
anyway.. did u mod anything about ur car? easiest thing to do is.. send to a workshop.. ask them do major service.. then should be ok di
