Magnefine vs. Spin on Kit

Magnefines are replaced as a unit. The filter part isn't replaceable. You just get a whole new one. You can get 'em on-line (google "Magnefine"), from NAPA, Ford dealers probably have them (there's a Ford part number for it), etc. They're not terribly difficult to find around once you start looking.
 
I've installed both magnefine and spin on kits before.
I will agree that Magnefine is easier to install.

I have the Spin on kit on my Ford F-150, plenty of room under the hood. Right now I have a FL1A on there, which provides about another quart of fluid in the system, attached to the return line after the cooler.

I want the magnetic ablility of a magnefine on the spin on kit I have on my truck.

I think this would be a great application for Magnefine's Forcefield oil pre-filtering device. Although kind of pricy, if it makes my transmission last longer it should pay for itself.
 
I think adding magnets to a spin-on won't hurt but I've also never seen any unbiased evidence that they pick up stuff that wouldn't have been caught by the filter anyway. You'd need a whole bunch of people with filters with and without magnets submitting ATF samples and then you'd have to correct for different transmissions and driving styles and see if it helped. At the very lest, you'd have to do the equivalent of the filter study with the talc power and use tiny metal shavings instead of talc. That would be easier and interesting. Unfortunately, nobody's done this, including the magnet makers. The websites of the magnet makers state their clams with nice graphics etc but they're biased. So, anyway, it's not going to hurt but I've just used free broken hard drive magnets instead. There's always the magnet(s) in the pan too. But like you said, transmissions are expensive and even the most expensive magnets out there are cheap by comparison.

As an aside, I also wonder how effective the magnets are as fluid is rushing past. I bet both the filter magnets and pan magnets do most of their work when the car is sitting and the fluid is still not when it's running and the fluid is moving. Though I'm really just guessing here.
 
BTW I ordered high temp Neyodemium magnets online.

When I drop the pan to a transmission I add a couple to the inside.

They are stronger and typically smaller than the magnet already placed inside the pan by the manufacturer and I figure that they will provide more surface area and metalic collecting ability than the OEM magnet.

Might just order a few more. I could use some more powerful magnets on the fridge.
 
I would wager, albeit with no real evidence what-so-ever, that a large high quality spin-on filter plus extra pan magnets would work better than the Magnefine because you'll have a lot of filtration and then the pan magnets will be acting on a lot of fluid that's sitting there stationary when the vehicle is parked. The obvious down side is that you have to drop the pan and the great thing about the Magnefine is how easy it is to hook up. The benefit to ease-of-installation ratio favors the Magnefine.
 
I hate Magnefine's Forcefield. But, I do recommend filter-mags or good ol' recycled hard-drive magnets for all those spin-on filters.

There is enough media, filtering capability, and filtering capacity in most spin-ons and I don't think you even need a magnet. Just a feel good mod! Anything the magnet picks up, makes more room for the regular filter media.

BTW, I don't find the Magnefine any easier to install than a spin on.

Excellent point.

Though I would add that on a properly designed transmission, it may extend the life. Whether this puts it beyond the useful life of the vehicle.... Well that likely varies by application.

It's a little more complicated in parts procurement. If space isn't an issue, then it's not much more than a couple of clamps and some zip ties..and some hose (if you have a hard time finding a fastening point).
 
I think magnefine is an excellent product, and a good choice if space and time are an issue.

But if your like me and want to hang another spin on filter somewhere I would go for it. To me, a spin on filter adds a few other benefits other than filtration. You get added fluid capacity and you change out a sizable amount of fluid each time you change filters.

here is my filter setup: https://bobistheoilguy.com/forums/posts/1775544/
 
According to Magnefine tech I spoke to, an acceptable time for replacement can be up to 3 years/ 30,000miles - if the transmission is maintained and driven under normal conditions - no overheating- no overload towing- and fluid changes according to manufacture spec.

I have had mine on for almost 2 years and inspect it every 6 months just to be on the safe side.

FYI- you can unscrew a magnefine filter for inspection and reinstall- no need to cut with a saw.
After 20,000miles I cleaned the magnet- the filter element looks like new.
