Will this filter fit my air box without modification?

Yes — it's designed as a direct swap into your factory air intake housing. No cutting, drilling, or adapters needed.

Do I need to clean or service this filter, or is it disposable?

Most high-flow filters can be cleaned with compressed air when they load up with dirt. Check the manufacturer care sheet that ships with your filter for the exact method — some are washable, some are one-time use.

Will this affect my fuel economy?

High-flow filters typically have a neutral to slight positive effect on economy since your engine doesn't work as hard to pull air. Real-world gains depend on your driving habits and tune.
