Ordered up 3 filter mags. One for the oil filter, one for fuel, and one for the Allison spin on. I know the Allison has a magnet already but what the hell.
I keep 2 magnets Russ, 1 that is in use and 1 cleaned and ready stuck to the lid of my tool box so I can just drop it on the new filter before even pulling the old one off... When I am cleaning up after I will pull the magnet off the old filter clean it and stick it on the tool box...
