Do I need tools to install this, or any special hardware?

You'll need a screwdriver to open your air box lid. The filter itself drops in—no extra fasteners or brackets needed. Standard five-minute job.

How often do I need to replace it?

That depends on your driving conditions. Heavy dust or off-road use means more frequent changes; highway driving extends the interval. Inspect it every oil change and swap it if it's visibly clogged or discolored.

Can I clean and reuse this filter instead of replacing it?

This is a disposable filter—designed for one-time use. Cleaning it compromises the seal and media integrity. Replace it, don't recycle it.
