How often should I clean this air filter?

That depends on your driving conditions. aFe recommends cleaning the filter every 20,000 to 30,000 miles for normal driving, but more frequently in dusty conditions. Inspect the filter regularly and clean it when it appears dirty.

What is the best way to clean and re-oil this filter?

aFe sells a filter cleaning and re-oiling kit specifically for this purpose. Follow the instructions included with the kit for best results. Do not use harsh chemicals or solvents, as these can damage the filter media.

Does this filter require any special tools or modifications to install?

No, this filter is a direct replacement for the factory air filter. It fits right into the factory airbox with no modifications required. Just remove the old filter and drop this one in.
