I recently bought a KN Air Filter... Ok, with the help of some of you guys, i've found the airfilter box on my 2001 CLK320...i counted a total of 6 locking clamps that holds the cover in place. I unlocked all the clamps and i still can't remove the airfilter cover. Am i suppose to yank the thing off? or is it suppose to come off easily? Or is there another clamp that's "hidden somewhere"? That filterbox is in a tight place and if there is a clamp hidden somewhere down there how the heck am i suppose to reach it?

Fellow CLK owners help please
