The air filter is located between the engine and the battery on the driver's side of the engine bay. To open it you first need to remove the big hose in front of it. You would do that by loosening the hose clamp with a Phillips head screw driver, and pulling the hose off the air box. Underneath the hose is two clamps. Flip those down and lift the top of the box up and then lift from the hinges in the r. You should have enough access to the air cleaner to remove it and replace it. If you need to remove it more you could remove the two electrical connections. One of them is on top of the box and the other on is to the on the side facing the engine. Then you could remove the hoses on the thing-a-ma-jig on the side of the airbox.
To put it back on, replace the top of the air box making sure the hinges fit back together properly in back and reclamping the airbox with the clamps in front. Then, if you removed them, replace the hoses on the side of the airbox and the electrical connections. After that push the big hose back onto the opening in front of the airbox and tighten down the hose clamp with the screwdriver.
