● Mounting parts: Air filter replacement

I have traveled 15000km since the last exchange.I thought it was time to replace it, so I checked it ...
What's this dirt!
After all, when I run around the dusty site, it looks like this (Photo A).
Of course, it will be replaced with a new one (Photo B), but it will be used by sandwiching a thin non-woven fabric on the intake side.
It may be better to use a normal filter, or it may be a relief, but after all I want to run while listening to the intake sound.
