Motorcraft FL-820S magnet trappings

I use the rare earth neodyium(sp) magnets. Extremely strong and cheap. I line them around the filter. Impossible to pull off. Have to slide them off. And watch your fingers around 2 of them. The attract very fast and will pinch your skin off. Ask me about it.
I'm not sure its the "be all end all" of fragment collection. But it helps. I am sure a good filter traps most of it as well.

Where can someone purchase magnets like that? No dead hard drives to snag them from.

The PureONE that I replaced this filter with has been on there for just shy of 600 miles so far and does not have a magnet on it. It'll be interesting to see if adding a magnet catches many particles, or if the filter media has caught them all already. Provided that the Mobil 1 doesn't keep making my engine shed iron like a mangy dog...
 
Will the magnets stick to the PureOne ok with the texture? I used some of that 'tin' tape by Nashua to hold my magnets on just incase.
 
That I'm not sure about. The paint is easy enough to scrape off, so I may take a razor blade and remove the paint from the flat spot on the dome end of the filter just to make the magnet more effective.

The type of magnet used for hard drives will just break.

If it's a super strong magnet it will stick to the textured PureONE with no problem.
 
How are you measuring the oil pressure? If it's via the factory gauge on the dash then don't worry about it. That isn't really a gauge anyway, more like a mechanical idiot light. It just moves to the "enough" part of the sweep when it gets a signal from the sensor. As they age they start to get weak or flaky and don't always point to exactly the same place. I tend to be a Ford guy but their gauges really frustrate me. The temp gauges eventually went to the same system. Why can Chevy install oil pressure and coolant temp gauges that actually tell you real values but Ford doesn't want to bother?
 
The Neodymium will stick very hard to a pure one. No need to scrape the paint. Get a set and you'll see what I mean.
You can get them on one of the internet auction sites as well.

http://www.unitednuclear.com has a nice collection of magnets (and lot of other cool stuff!) Their prices are reasonable, but shipping is expensive for small orders. The three pack of the 3/4 x 1/4 disks looks about right. (These WILL stick to a PureOne filter....)

Most Radio Trash outlets have mediocre button magnets.

I stuck one on the end of the PureONE that's on my car right now, and it grabbed on real tight. I don't think the paint is going to bother much.
 
What weakens those magnets overtime is heat. They will eventually loose strength and get weak enough that they fall off.

I have noticed that my FilterMag has weakened slightly since I bought it new. When it was new I needed a screw driver to pry it off and now I can pull it off with my finger if I pull hard enough.
 
My filter is pretty much directly below my left side exhaust manifold and the magnets get fairly hot. They're still really strong, even after about 10,000 miles of being down there. I wonder if that non-magnetic backer plate is protecting them somehow?
 
My filter is beside a catalytic and exhaust pipe and has been there for 200K KM (120K miles) and are just weakening now as stated above. Not bad for that mileage.

Nice! ... here's a more direct link:

http://www.unitednuclear.com/magnets.htm

Off the unitednuclear website:
"These Neodymium magnets are made to very demanding standards, however uses should be restricted to operating temperatures below 180° Fahrenheit (80° Celsius) or they will lose their magnetic properties."

I'm sure they would last some time as others have said from their experiences using these type of magnets.
 
Yea, UN has lots of toys!

AFAIK, all Neo magnets will degrade when hot. I'm using 6~7 UN 'pill' magnets on my Honda. After about a year's use the magnets seem to have weakened slightly, but are still plenty strong, requiring real effort to finger-pluck from the filter. I think UN is just being conservative and honest. I don't get the impression their magnets are inherently less heat tolerant than generic neo stock.

You've got me curious. When time allows, I'll attach a thermocouple to the oil filer and attempt to measure surface temps.

You can get high temperature neodymium magnets..
