Yea it is fine to run your car with out a filter.you can make up a mesh thats FINE too but what (( I )) would do is get a pair of tights and put it over where the air filter was ment to be, works much better then a mesh ((BUT)) tell the girlfriend 1st be4 yea rob her new tights are yea will get this :slap:
