Just to note after itchy boots mentioned her issues with her air filter I checked mine and I agree they don’t fit correctly potentially allowing dirt into your air box and engine. My filter is the 152598
I was told to try 152599 but that’s actually worse.
The darker foam area should be flat but the filter seems to be too small causing significant curving to the filter face.



I have contacted TwinAir and I will be sending them my filter frame.
They intended to make new filters once they have received it.
