Do I need any tools or hardware to install this?

Basic hand tools handle the swap. Your air box clips or fasteners are reusable — you're just lifting out the old filter and seating the new one. No additional hardware needed.

How often should I replace it?

Follow your vehicle's maintenance schedule, typically every 15,000–30,000 miles depending on driving conditions. Check it visually if you live in dusty areas and replace sooner if clogged.

Will this affect my fuel economy or engine performance?

A clean filter restores airflow restriction caused by a dirty one. You'll notice smoother acceleration and better throttle response compared to a clogged filter—not a modification change, just returning to normal operation.
