    Most aftermarket air filters are constructed from multiple layers of cotton gauze, which are sandwiched between wire mesh that is formed into pleats. The layers of oiled cotton fibers are able to trap dirt particles that are even smaller than the holes in the filter media. The airflow stays consistent between cleanings, for optimal combustion.
    The easiest way to improve airflow to your engine is just by changing your stock air filter to an aftermarket performance air filter.
