My companion just bought a 2008 450ER for ATV MX riding. Previously it was only used on ice road racing and thus didn’t have the original air filter fitted.

Now I’m trying to install the foam filter back on, but I’m having trouble shoving the metal filter body into the air inlet tube. I can’t get it all the way in, it sits at about halfway and only twists to different angles from there.
It feels like the filter body is too big or that the inlet tube is shaped like a cone. Is this how it’s supposed to be?

My guess for now is that it just is like that, and the small metal part in front of the filter and the metal band around the foam filter’s rubber sleeve would keep it in. (Only that I’m missing that small metal part for now.)

How it sits in your TRX, any tips how to fit it properly? Thanks in advance!
