K&N 33-2238 Air Filter Product Reviews

Thursday, August 20, 2015 - Part 33-2238
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.

Great part. The only thing I failed to realize was this is a dry filter not an oiled one so I accidentally put oil on the filter. You guys should make these filters a different color or something so it's not so easy to make that mistake. I thought all k&n filters were oiled filters.

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.
