How often do I need to replace this filter?

Most drivers swap them every 15,000–30,000 miles depending on driving conditions and air quality where you live. If you're in a dusty climate or tow regularly, inspect it every service and replace sooner if visibly clogged.

Do I need to clean or oil this filter before installing it?

No. This is a dry-type pleated filter—it installs ready to use straight out of the box. Do not oil or wash it; that defeats the filtration media and will reduce engine protection.

Will this work if my air intake has been modified?

This filter is designed for factory air box dimensions. If your intake has been replaced with an aftermarket system, verify the filter diameter and mounting style match before ordering—some cold-air intakes use different filter sizes.
