Can I clean and reuse this filter multiple times?

Yes. Gently tap out loose debris or rinse with low-pressure water and allow to dry completely before reinstalling. Avoid high-pressure washers or compressed air that could damage the panel.

Will this filter restrict airflow compared to the stock filter?

This is a direct replacement designed for the factory airbox. Performance difference will be minimal; the main advantage is the visual upgrade in the engine bay. If you're building a high-flow intake system, check compatibility with your specific intake design.

Does this come with new gaskets or seals?

Filter unit only. Your factory airbox gaskets and seals should be reused if they're still in good condition; replace them only if cracked or deteriorated.
