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.

Aside from the superiority of K&N air filters, putting one in my mower just makes financial sense. Each disposable filter costs around $10 and I use no fewer than three of them each Summer and sometimes more than that. It's a no brainer to buy the K&N filter for less than one Summer's worth of air filters and never have to buy another. I use your filters in my motorcycles on and off the track and in my truck, and wouldn't consider any other product. What do I think about K&N air filters? I think you should keep up the good work.

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.

There was not a direct cross reference for the filter I had in my field trimmer. The flat outside rim on the new K&N filter was a tad thicker so it took some extra pressure to close the filter box lid, but it'll get used to it I am well pleased with it.
