Using this K&N air filter is easy. First, make sure your vehicle's engine is turned off. Locate the old air filter housing and carefully remove it. Then, take out the old filter and replace it with the new RF - 1047 filter. Ensure it's properly clamped in place with the 3 - inch flange. When it comes to maintenance, check the filter regularly. If it looks dirty or clogged, it's time to clean it. You can use a K&N filter cleaning kit to gently clean the oiled cotton media. Let it dry completely before reinstalling. Also, be careful not to over - oil the filter during cleaning. This can affect its performance. And always follow your vehicle's manufacturer's guidelines for air filter replacement intervals.
