Using this K&N custom air filter is easy. First, make sure your carburetor is turned off and cool. Then, remove the old air filter and replace it with the K&N custom filter. Align it properly with the carburetor and attach the custom chrome top and base plates. When it comes to maintenance, the K&N air filter is washable. You can wash it with mild soap and water when it gets dirty. Let it dry completely before reinstalling. Remember to check the filter regularly, especially if you drive in dusty conditions. If the chrome parts start to look dull, you can use a chrome cleaner to make them shine again.
