Fit my Toro push mower's Briggs 6hp perfectly.

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.

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.
