that depends on what you want to do. If you're removing the restrictive elbow and than reinstalling the factory airbox you simply use the filter you have or install a K&N filter (Autozone; Advance; etc..) because without the restrictive elbow you get more air flowing into your factory airbox once you reinstall it.
or, as Spazz says....forgo the factory airbox and put on a cone filter by either using his setup of the Calmini version or get a cold air intake from
Morgan-Tec.....etc...
Your Factory Airbox gets its air by sucking through what is likened to a flattened straw! By removing the restrictive elbow...you let your factory airbox breath easier...and by tossing your current filter and adding a K&N to your factory airbox....it breathes easier yet.....and by tossing your complete factory airbox w/ filter and going to a cone filter setup via Calmini or a cold air intake w/ cone filter by Morgan Tech it'll breathe even easier...get it?
it's all progressive...how much you want to do depends on how much you want to spend.
remove elbow & reinstall factory airbox----your time
replace factory air-filter with K&N filter to factory airbox---something like $40
remove factory airbox&filter; go with Calmini-----something like $80 I think
remove factory aibox&filter; go with Morgan Tec cold air intake & cone filter--
around $200 depending on powdercoating choices.
