Sure mate, I got it from ebay off this guy: Ebay Member
And the product website is: www.filtermag.com
If I remember correctly the website has alot of pics of filter's cut in half... take them as you will, no doubt they only posted pics with the largest build up of fine iron, but in all honesty I can't see how it wouldn't work, since the dirty oil passes through the outside of the filter past the magnet before being pulled through the filter core. I've also heard that the A'PEXi UFO filters use a magnet aswell. The benefit of this one is that you can swap ot over to your new filter with every oil change.
