hello everyone!!! i just bought an air filter and after seeing someones pick i am wondering what to do! do i put my drop in k & L filter in the black box or do i totally remove it and but the filter in as its replacement?!? i need some help! thanks

 

what type of filter did you get? cone or square shape?
if cone, you will need an adapter. if square, same as stock, just replace yr old one.
