Hasn't it occurred to you that the real purpose of any air filter is to trap abrasive particulates, and by extension, if it's successful at that task it will necessarily dirty-up? That crap you see on the paper air filter is dirt that didn't make it into the engine. A clean looking K&N is an improperly oiled K&N merrily saying, "Permission granted." to dirt asking to come in. (By the way, the traditional test to judge whether a paper air filter is clogged is to remove it and look through it towards the sun. If you can see light through it, the filter's still useable.)
