Will this fit my Prius without any modifications?

Yes. This filter is designed as a direct OEM replacement — it seats into the factory air box without cutting, drilling, or adapter hardware.

How often should I replace this filter?

Follow your vehicle's service manual for replacement intervals. Most drivers swap their air filter every 15,000–30,000 miles depending on driving conditions and air quality in your area.

Can I clean and reuse this filter?

This is a disposable filter element — replacement is the intended service method. Cleaning may damage the media and compromise filtration performance. Always install fresh.
