K&N Air Filters would like to have a word…
I literally never change my air filter during oil changes because once a year I take my K&N out, treat it and put it back in. They work better, they produce less waste and they pay for themselves after a year.

The reason I do it myself is because they’ll use a generic crappy no name filter and oil with no additives for older engines or anything.
