I was watching speed channel yesterday and they were demonstrating these new filter magnets. Powerful magnets that clamp onto the outside of your oil filter or tranny pan and trap harmful metals near there and keep those metals from damaging your engine/tranny.

Anyone think these are decent products? Junk?

I think the site is www.filtermag.com

 

I recall reading that filter magnets are more science fiction than science. Though I've never used one I would tend to suspect that they're not going to do you much, if any, good.

 

I'd put those magnets in the same general category as the "tornado" and all those "slicker-than-snot" oil additives

 

Many manual transmissions already use a magnetic drainplug from factory to attract metal from getting recirculated onto the gears. But keep in mind this is because they are sealed and not filtered.
But for filtered apps, I would question it as I would think an oil filter should do well enough in capturing metal filings.

 

Wrong,

These things work well. I have them on my boat engines. While I don't have pics of what they grab, they DO work rather well. They will grab small metal pieces and hold them till you dump the filter. The magnet goes from filter to filter. It is cheap insurance for $30.

Here is a pic of what I use them on.
If you look close, on the left engine - look at the blue filter on the bottom right. You can see a black/silver filter magnet on the filter.

 

Dayum... that looks like it is a helluva fast boat!!

 

The words 'SUCK MY WAKE' come to mind......how many ponies are those good for?

 

I'm a believer!! I have them on all 4 of my fords! One of the fords I own is an 01 taurus, at 32,000 miles I changed the trans fluid and filter. When I dropped the pan I saw a quarter sized magnet in the pan, that thing had what appeared to be grey mud/sludge all over it!! Oh yeah it was metal I relized then all that stuff had passed through the filter but stuck to the magnet. With out that magnet I think that metal, no matter how fine would be like valve grinding coumpound to all the internal working parts. My 03 Mach-1 has one on the trans, and the high performance version on the oil filter. I believe these two items are a big plus for anyone who plans on keeping their car for many years

 

OK, Y'all have convinced me that filter magnets or something similar are worthwhile.

And I second the comments about the boat. Awesome!

 

575 HP each.

She'll run 90 mph.

 

Griot's Garage www.griotsgarage.com has them in various amounts (number of magnets). Part number 47251. good pic where they opened up an oil fliter and show what is where the magnets were.

 

Would attracting all that metal inside the filter cause an issue with oil flow? I suppose not, but I had to ask

 

How would you ever know it there was metal in the fiter?
