Automobile Repair/Nissan/Maxima (4th Generation)/Changing the air filter

The air filter keeps dust and other particles from getting into the intake and damaging your engine. So it is important to make sure that it is clean, because as dust builds up it will restrict air flow to the engine. How often it needs to be changed, depends on what conditions you drive in. right|thumb|250px|Fig. #1: This is the filter box.
