K&N Drop in Filter

i just replaced my stock filter with the K&N drop in but didn't remove the charcoal filter. will just replacing the filter (kept charcoal inplace) give even the slightest difference that a person driving can notice? i read about removing the charcoal filter thread but don't know if its good for the engine or not cause i think they placed it there for a reason, but if removing the charcoal will make a even GREATER difference then maybe will think about it.

i know many of you will say Intake FTW but i think i will do the drop in first and see how it goes.

anyone that has either replaced the stock filter and/or removing the charcoal filter too please feed me with some input. thanks

(everything here is about stock intake)
