Engine breather filter

[Windycorner]

I am missing the filter for the engine breather in a the air box from my 400/4, I have the 2 steel mesh parts, I presume it's a foam filter would this be correct and how thick is it approximately.

It's about 1.5-2.0 cm thick, well its the depth of the recess anyway. I made mine out of one of those kitchen sponges with the green scratchey bits on top, cut to size. Works a treat.

That's a good idea nurse Julie I will make straight away cheers.
