Was doing some research on GSX-F engines and found this on the FastLarry's website.
K&N Air Filter
Many Bandit owners choose to put a K&N filter on their bikes. There are trade-offs for everything and this is no exception. While the K&N filter is reusable and offers increased airflow for about the same price as a stock replacement, it also allows more dust particles to enter the engine. The Motor Industry Research Association found that K&N filters stop 97% of particles on an SAE fine dust test (0-20 micron particles). By comparison, the average paper filter stops 98-99% of particles on the same test. This means that the K&N passes 2 to 3 times as many particles as a standard paper filter. It is up to each individual owner to determine which filter is best for them, K&N or stock. While the K&N allows more dirt particles to pass through the filter to the engine, the decreased long-term cost and increased power often outweigh
