I purchased a K&N 33-2238 Air Filter for my Toro SR4 Super Recycler Mower 21 inch. So I don't have to keep buying paper filters. Wash it let it dry & reinstall. Have K&N Air Filters in everything I own. It's a no brainer better performance and never have to buy a filter again.

All totally satisfactory. Nothing to add.

Once again, a five star experience with K&N. We use your air cleaners in three of our four vehicles and now in our Honda lawn mower. It runs so much better, if it was dynoed it would probably show a 15 increase in power. I'm fine with paying a little more for a lifetime cleaner, it amounts to about five stock paper cleaners that would be used in one season, a no brainer.
