This company offers inline magnetic filters which also have a traditional pleated paper element.
A friend of mine recommended it and I thought I'd see what you guys think.
Installation is simple - you just mount it in the cooler/radiator output line. You do need to use one of those "wheel" pipe cutters.
I once worked in a transmission shop in Montreal Canada. The owner believed that an added, permanent transmission "filter" added unnecessary restriction to the flow of fluid.
He did use them but here is how.
After a major failure and overhaul, he would add one of these filters which contained powerful magnets to the outlet line returning to the automatic from the radiator.
All transmission lines, etc were flushed, but while they were testing the overhauled automatic, they temporarily added that filter, primarily to attract any ferrous metal leftover when the transmission self destructed. Remember just like AC repairs, the slightest trace of anything is a disaster. Ferrous metal sticks to the magnets inside. Valve bodies can stick, governors (not used any more) can stick. Modern flow solenoids can become fouled, neccesitating pulling the pan again to fix it.
The car would come back after being driven two weeks, and the filter was removed and thrown in the garbage. (All the dirt or metal that is going to move will move during that two weeks) It had done its job.
Cleanliness is the key word. Unless you are abusing stuff, clean stuff tends to stay clean.
