Using this K&N Performance Airbox is easy. First, remove the old factory air filter and air box. Then, connect the new air box to the factory air intake hose. Make sure all connections are secure. When it comes to maintenance, check the filter regularly. If it looks dirty, remove the lid (it's easy to do) and clean the filter. You can find the proper cleaning instructions in the K&N manual. As for the air box itself, it's built to last, but keep an eye on the connections over time. Before installation, always double - check if your vehicle is on the list of compatible models. And if you have any questions about the TUV regulations, refer to the K&N catalog or website.
