open the hood and look for a black plastic box about 6 by 10 inches. It will probably be on the drivers side near the front of the car with a large tube ( 4 inches in diameter) leading to the throttle body. there will be two wire loops on the side which hold the top on. flip open the loops, remove the dirty filter, blow out the debris from the inside of the box, drop in a new filter , close the top (be sure to insert the tabs on the other side from the loops into their respective slots), snap the loops over the top and you are done.
