Changing air filter on a 98 nissan maxima?

where is it located and how do i do it?|||Don%26#039;t know about your stated car but air filters are usually located in black plastic box shaped containers. There wil be a big hose going to it and another part that will have an open end to let the air in. Usually has clips or screws that hold it closed. Remove the clips/screws and open it up. The filter will be sitting right there, just lift it out being careful to keep it flat so the dirt/dust and other crap doesn%26#039;t fall into the air box. Remember which way it is facing and replace with a new one. Really simple to do. Get under there and look around you%26#039;re bound to see it.
