If you are referring to a K&N airfilter, they reduce restriction at your intake, allowing better airflow, improved performance and acceleration. A little pricey but, in the right application, definitely worth it. I'll explain ....
K&N airfilters are available for automotive and motorcycle applications. In automotive, the filter element is installed as a replacement for the disposable paper element in the "airbox" ( the filter housing in the engine compartment ). While the new K&N filter does offer the potential for the intended performance enhancements, the design of the "airbox" itself hinders it and makes it less efficient. K&N also offers a "Filter Charger Kit" for automotive, that does away with the "airbox" and stock air intake tubing which works very well and offers a noticable improvement in acceleration and performance.
In motorcycle applications ( and I can only speak from my experience with my Harley Davidson application ), the stock airfilter is, again, in an "enclosed" housing. The K&N filter kit does away with the "backing plate" of this housing and allows room for the bike to draw the larger amount of air from. The K&N filter, again, reduces the restriction at the intake and improves performance and acceleration. Fuel injected motorcycles will have to be "re-mapped" to get full benefit of the increased airflow. Carbed cycles should be adjusted for the same reason.

Unless you add a special intake ram-air as well, just dropping in a K&N filter is a complete waste of money. You get more intake noise and worse filtration.
On small displacement bikes, the HP gain is so miniscule, and at such high rpms, that it's not worth the price of risking more dirt in your engine.

If you are refering to a K&N air filter, it is a free flowing air filter that is supposed to increase performance. Previous answer is correct though. Waste of money.

obviously none of the previous people have ridden small bikes. it is possible to get a substantial gain in performance (95mph Honda XL125!!!) but you have to do other mods or it WILL be slower than before you started.
If you dont know what your doing, save the cash for a bigger bike
