Assuming you want to check or replace the air filter... There is a big black plastic box on the driver (left) side of the engine. It has 2 spring clips on the end nearest the left fender. It also has a hose about 3" diameter that has screw clamps holding it in place. Pop open the spring clips, and loosen the hose clamp screw (the one closest to the filter box) and you can lift the lid on the box to expose the filter inside.
