Hi
they fit where the sump plate goes
so they are held on by the 6 small nuts..
not much on a large sump...
I have the small CB Performance one on My beetle
You take the original strainer out
and use the strainer/filter in the sump
so I only use one thick sump gasket plus the washers etc
I fitted this mainly for the extra fine strainer which works great..
I know of one fellow who actually uses a motor bike filter inside the small sump...
the larger ones which are really compulsary for racing etc
use a lot of extra oil..
so the oil change gets a bit expensive... lol
I should have taken some pics of My sump as i had it off yesterday changing the oil...
cheers
