How do you change air filter on 2001 volkswagen cabrio?

the air filter is in a black box with a big hose on it, going to the engine...and a couple of clips holding it on...unclip the box lid, and lift gently so as not to damage any hoses....wiggle out the filter and slide in the new one....re-clip...and be happy:) also, you should be able to find a shop manual at the library, you'll have to make copies of the sections you want as they are reference only, but everyone should have a regualar manual for their vehicle, available at an auto parts store....may the force be with you :)
