Scotty, I just got a new Air Filter for my 2013 Mazda3 Skyactive at Auto Zone, The kind I got is Called K&N Filter and It's washable and reusable, how often should I wash it?

About once every 50k miles. And you'll need to re-oil it carefully using K&N filter oil.


Oh yeah that's also something I forgot to ask is, if there is a specific way to wash it or not, but thank you though

unless you're taking it to the track, ditch the K&N

Putting oil on the K&N is going to mess up your MAF.  Just use a plain, dry paper filter.
