Well, neither can be used with the stock filter arrangement. The only way to get a magnet in the mix would be a drain plug. That said, the spin on oil filter adapter would allow use of a conventional filter and Filter Mag. The only reasoning behind the use of a filter mag over the mag dog is ground clearance. The Napa Gold 1042 filter with the spin-on adapter preserves the same ground clearance.

There is a shorter filter we use with the accusump input adapter, but it's not as heavy duty, and quite frankly, it has so little area it needs to be changed about every 1,000-2,000 mi tops.
