To use this K&N plenum, first make sure your engine has a Weber DGV carburetor. Carefully install the plenum and adapter according to the engine's specifications. When installing, ensure all connections are tight to prevent air leakage. During use, keep an eye on the airflow performance of your engine. If you notice any changes in engine power or fuel efficiency, it might be time to check the plenum. For maintenance, clean the plenum regularly. Use a soft brush to remove any dirt or debris. Avoid using harsh chemicals that could damage the black finish. Store the plenum in a dry place when not in use to prevent rust and corrosion.
