Seems like something that belongs on an infomercial.

 

It must work though. I just got this magazine in the mail and saw this. It must be good especially when the car is new....I think :scratch:

 

I'd have to think that if was a good idea, that Fram would have it built into their filters. Who knows.?

 

Another thing - by the time any metal shavings get to your filter, they should be trapped there. - I hope so anyways.

 

I guess your right.

 

if you like the idea take an old speaker and take the magnet and use it, cant be any different from the product they are selling

 

looks like you are paying 20.00 for a large MAGNET :notnice:

 

My father used to own a car which had 2 round magnets in the oil pan of the automatic gearbox. Those made sense.
Like Danny said, stick an old speaker magnet to your filter and you've just saved yourself $20. As for the effect... I doubt there is any.

 

I sure that works good on my ALUMINUM mustang engine

 

I am trying to remember the name of the company but there is a manufacturer that makes replacement oil drain bolts that have a magnetic tip. This way when you remove the bolt to drain the oil you can see what metal it has captured and easily remove it.

 

A magnetic drain plug works great to show wear on the lower unit of a boat motor. But, that lube does not pass though a filter. I guess if there was some fragment that came from the bottom end then it might be nice to stop it in the pan. But, I also think that if there is a fragment big enough to cause a problem if it recirculated back to/or through the filter. Stopping it at either place would be the least of someones worries. I thought the idea of a filter was to trap the contaminates in a fluid

 

Are the internals like rings, cylinder walls, valves/seats, etc. aluminum or just the major forgings/castings?

I recall the old Chevy Vegas ("Groan!") had largely aluminum internals (unsleeved cylinders, I think) that were worn slap out at 50,000 miles and no real way to rebuild (not that anyone should want to....).

 

I'v seen them in the Jegs catalog.

 

I had a magnet drain plug on one of my other cars, and when you changed oil there would always be a small amount of shavings/matalic sludge on the magnet/drain plug. I saw a wrap around cover with magnets in the Groits catalog which is very similar but a lot more $$$$. I dont know if its necessary or not but what can it hurt.....

 

FWIW - The pistons are cast aluminum Hypereutectic. The Cylinder walls are ductile iron sleeves cast in place. The Valves are stainless Steel. The Valve Seats are hardened steel.

The magnets do work, but are one of those things that just don't add a significant amount of value. The amount of filter material in the pleats is substantial enough to hold a vast quantitiy of particulate matter that is expelled from the wearing process. In other words, yes it works, but no it's not needed..

Now don't get me going on fuel line magnets... :bang:
