Magnets in the OIL filter ?

[nytro addict]

At my local dealership they sell these little magnets that go inside the oil filter. I was wondering has anyone tried this? Obviously its suppose to help collect any shavings. But my biggest concern was what if the magnets come out an go into the motor.

I have seen magnetic covers for filters but never one that went inside the filter. I guess it depends on if the magnet is in on the inlet side of the filter. Is the inlet the inner part of the filter and the outlet the outer part? If its on the inlet it will only get sucked into the filter not into the engine. You have to ask yourself tho if there is something getting caught on the magnet WHY is the filter not picking that same material. On my first filter change on my 03 RX I cut the filter apart and there was A small amount of metal in there from initial break in. So I would almost think that the magnet is for the resulting poor performance of poor quality "OTHER" brand filters.

the magnet wont fall out.. but its really not necessary. If you are worried about the filter plugging and bypassing, just change the filter everytime you change the oil and you will be fine. rather then the yamaha recomendation of what 12,000(someone correct me if im wrong) miles?if its that bad, more then likely theres something more thats wrong and the magnet isnt going to solve an internal engine problem. Like mikey, i cut my filter open on my nytro after break-in and it was really clean for being a break-in filter..

Isn't the engine almost all Aluminum? Ok not the rings, valves and piston pin. The other thing is that if anything makes it to the filter how is it going to get past that? What is the point???

Like Mikey said, cut the filter open. I've done this a few times and I think once I saw junk in there.

Not much iron to catch on the magnet. Hardly seems worth the effort. However, ... They do have a magnet attached to the inside of the spin-on oil filter on my truck's Allison Transmission. Most of the components on that truck are aluminum. When I changed the filter last week, there was some sort of sledge coating the magnet. So, in that particular application, I can see the benefit. This magnet was a 1/4" thick donut placed around the boss where the threads that fasten the filter are.

I would see no need for a magnet in there -- unless maybe during initial break in if you're worried about metal shavings. But those filters are really good and should remove any shavings anyways. That is the purpose of a good filter, right????

I changed my filter after 476-ish miles initially (what a PITA!!!!) and then a week ago, before this season (my machine's first season was this last season). I did change the filter again, but I feel I really, really did not have to. Everything was clean and look ed brand new...... I think the filter on these machines can wait until every other oil change or so.

But of course I just received my new Ulmer's oil filter relo kit so from now it's clear sailing for me!!!!!!!

find an old magnetic CB antenia and get the round manet off of it. Just place it on the outside end of your filter, it is strong enough to hold the crap on the inside right where the magnet is. We do it on our wet kit on the trucks. You'd be surprise if you open a filter how much stuff it cathes this way. Maxdlx

I've always used magnets on the outside of filters on all my cars to catch very fine metal particles that could pass through the filter media. In the same manner, I have done the same for my Venture after its first oil change. I used very strong rare earth magnets. Also used very strong old computer hard drive magnets that are semi rounded. Putting magnets will not hurt anything, even if the majority of the parts are aluminum.

One thing I noticed, the dipstick for the chaincase is supposed to be magnetized (according to the manual) but is not or very weak. I attached a small rare earth magnet to the dipstick. Now this is a place where a magnet is required.

I have seen magnets used by OEM's in manual transmissions, differentials and 4X4 transfer cases since there is no filter in any of these. Even automatic transmissions have a magnet in the pan even though it has a filter. It always has a bunch of very fine metal sludge.
