I've been using K&N for years. They haven't disappointed yet. The picture of the grey cylindrical filter on Amazon is not correct, but if you look up the part number on K&Ns website, it shows the correct filter.

My dad gave me his old 1983 Husqvarna 181se that had a bunch of work done to it back in the 1980s when he was a logger. It had an old cone filter that comes out of the top cover and it had been smacked around a bunch so I wanted to replace it. After taking some measurements I found that this one fit what I needed. The filter fit perfectly and the saw is breathing easy again.
