A K&N air filter.
To clean a K&N air filter, you typically use K&N's own cleaning solution, which is specifically formulated for their filters. This cleaner is designed to effectively remove dirt and debris without damaging the filter media. After cleaning, the filter should be re-oiled with K&N's air filter oil to maintain its filtration efficiency. Always follow the manufacturer's instructions for the best results.
If it is a stock paper filter, no it needs replacing, if it is a k&n high flow, yes, clean it with k&n filter cleaner and rinse with gentle running water let it dry and oil the filter with k&n filter oil.
