I love the thing (33-2238). I won't need another air filter for awhile. A+++. I've got a K&N in my truck and my Harley, soon for my '81 Kawasaki.

I ordered a No.33-2238 hybrid filter for my Toro Recycler Personal Pace walk behind lawn mower because the OEM paper filters were getting so dirty that I was replacing them about 3 times per season. I use the mower for mulching leaves as well as mowing the grass, so it gets a lot of use. The K&N filter fit perfectly, and the engine ran like new. I'm looking forward to cleaning the filter as necessary and just reinstalling it again instead of spending $10 for a new one about three times each season.

Outstanding service in receiving the new filter for my small engine lawnmower. Superb quality and great replacement for my other filter. Love these K&N filters.
