Just change the element to K&N will improve airflow at a fraction of the cost. It is well made and often the maker of high flow performance reuseable air filter elements, typically around $50 or so and a bargain. Changing airfilter only usually is able to be compensated for by the existing computer and EFI system should be fine. If you change the exhaust system in the near future though, the air fuel mixture may be too lean for the stock settings to compensate. Look into Dobeck' tuner or similar if the latter is the case in the near future. JMHO :s
