First off, was it black from dirt, or was it oily. If its oily, you got something else going on. Chances are, your PCV is plugged, and oil and air is going out the wrong way from the engine into your air filter. That will start to build up and restrict ariflow, killing performace, possibly throwing a code. PCV are cheap and easy to fix too
