What is needed to change the air filter or Cabin filter? are they the same unit?

They are two different filters. The air filter is to filer the air that the engine uses, it is under the hood. The cabin filter is the air conditioning filter (like the ones you use at home). It is under right side of dash, you have to pull carpet back & lower a panel. It is just above where passenger's feet would be. Takes about 20 minutes to change. Howard Cassels Garage, Inc
