Oil Filter Outside Magnets???

So I saw these FilterMag wraps that go on your oil filter to attract/trap small metal shavings. Sounds like a great idea, but they want quite a bit for them.

Default Oil Filter Outside Magnets???

So I saw these FilterMag wraps that go on your oil filter to attract/trap small metal shavings. Sounds like a great idea, but they want quite a bit for them. And they are not even niobium (spelling?) magnets. So for like $8 or $9 on Amazon, you can get a set of niobium this bar magnets. So I figured I'd put 5 or 6 of those on the bottom, outer circumference of my Z's filter, and put a zip tie around them for insurance. Then, next time I change the oil, I'll cut it up and see if I find a lot of extra metallic gunk by the magnets.

Has anyone already done this??? Thanks.

I know of a couple of people who have done this. But not on a Z. Can't tell you if it works or not.

you'll want stronger magnets for the magnetism to go beyond the oil filter casing. the reason the real deal is so expensive is because its a whole lotta magnet. not that frig door stuff.

You'd never know if they work unless you cut filter open.

Also, they can be more harmful than good. If filter ever goes to bypass, even if oil is cold, there is a danger that those particles will get "washed" away from magnet and drawn into system via bypass port.

I'd rather have the metal stuck to pleats. Yes, they can get washed away too, but probably better chance they won't due friction and surface retention.

It would have to be a very strong, quality magnet as you suggest. It wont help you with Aluminum bits.

There is a company that makes a small micron screen that goes on top of the filter, between the filter and the block, that would probably be more useful. I think the magnets would have to go inside the filter to do any good. It might would work on the outside if the filter case was aluminum.

I remember a thread or conversation on here about a long time ago. Just as this time some say it works orher say you are better off just letting the filter do its thing. I can't remember who said it but they said the same thing you did, go big or go home. He recommended magnets out of car stereo speakers. Them things are beefy LOL.

What happens if that screen gets clogged or restricted though

If we were talking about an old school engine (pre-80s or so), a magnet might do some good - plenty of ferrous metals floating around. There's not much Iron in an engine nowadays. Plus, as pointed out above, it has to be a powerful magnet to penetrate the steel filter housing. I'd use a magnetic drain plug (if I were going to use a magnet).

I use a magnetic drain plug in both cars. It is just metallic goo, nothing more. I don't see magnets doing anything on the filter. If there is anything larger than the goo on the drain plug magnets are not going to help as it's already too late

There is an Aircraft Oil filter that has magnet on inside. (Tempest) It's glued to case, but 9 out of 10 times, that glue has failed and the magnet is free to shake around. Never seen metal on them.

Champion aviation oil filters do not have magnet, but use higher quality materials. and about $5 more expensive. They also reason magnet not good idea since big chunks can be washed away.
