Replacing these filters is easy: You simply buy a new one for your vehicle's make, model, and year, lift out the old one, and drop in the new one. A few older vehicles have permanent air filters.
DIY: How to Replace Your Air Filter
To see if your air filter needs to be replaced, shine a flash light from the inside out. Be careful that no dirt or debris falls into the carburetor. Clean the inside of the air.
