Will this filter fit my factory air intake box?

Yes, this is a direct replacement that installs into the OEM air box housing. No brackets or adapters needed.

How often should I replace it?

Follow your vehicle's service manual for maintenance intervals. Dirty air filter conditions vary by driving environment — check it visually every 15,000 miles.

Does the red color stay or will it fade?

The finish is applied to hold up under normal engine bay conditions. Extreme heat or prolonged exposure to harsh chemicals may affect appearance over time — typical for any engine component.
