Just to explain a little further for you. If you take the top off the airbox and remove the filter, you will see a curved cone shaped piece about 5" long IIRC. Just hook your fingers under the front of it and give it a sharp pull, it will come off. It's as simple as that

Basically it allows a greater volume of air to spread out over more surface area of the filter. If you look at your old filter, the dirt build up will most likely be where the horn exit was. Removing this allows greater air flow (essential for a diesel engine to get lots of nice cold air). You won't see your car 'taking off' F1 fighter style, but you should notice a slight difference for the better.HTH
