An air filter has nothing to do with the volume of air an engine ingests, unless the filter is overly restrictive.

The filter stops particulate matter from entering the engine. I'm sure that you may believe that all is OK with your engine, but it's a matter of "when" not "if" problems occur if you run your engine without an air filter.
