I would like to know about the MTF-94 also.....what brand do you use?

 

10 micron oil filters crap now I have to find a 5 micron that will work. I had no idea the filters in my car let so much crap through. Back on topic H-D twincam motors (current since 1999 use 5 micron filters and magnetic drain plugs. So yeah I think they're worth it. (now to add this to the list of things to buy for the cars)

 

I've got an '08 Impreza STI. What do I need? engine/diff/tranny?

 

Just a quick plug for Mr. Dimple and his wares. He was a pleasure to talk with on the phone (after I screwed up the ordering on his website). We eventually got the "3 for 2" deal worked out.

Delivery was very quick. The plugs look very nice and, man, those magnets indeed are not kids' magnets. Thanks, Richard! :cornut:

 

I wish I would of gotten 3 of these sooner. I just changed the Engine and tranny fluid a couple weeks ago. Oh well I will get them the next time around.

 

Stupid question, but, is the 3 for 2 deal still available for forum members? Thanks

 

They have not ended the offer yet so mention it on your order or call them. I know this company very well and they appreciate the patronage MA gives them.

 

As soon as you make one that fits on a Fumoto drain valve, I'm on it!

 

......or for the OEM oil temp sender.

Wonder if I should just epoxy on a neodymium magnet to the pan?

 

I think the trick is getting a rare earth magnet that is both strong and not temperature sensitive. Many magnets with loose their strength when exposed to high temps.

 

If the oil temperature or coolant in your MINI ever comes close to the magnetic strength field of a magnet decreases the magnet is the least of your worries! :lol:

 

Oil gets hot enough to effect an ordinary magnet every time you run your car. So does the coolant. So I don't understand what you mean.

 

Well did some checking and found that the magnets used in hard drives are [ame="http://en.wikipedia.org/wiki/Neodymium_magnet"]neodymium[/ame] and the temp range is way above what we might see in our vehicles.

Lets see if I can come up with some way of attaching it to the oil filter canister and see how it works.

 

The temperature of the engine oil will affect the magnetism somewhat, but not enough to render the magnet ineffective (in attracting metallic debris). The Ts at which the magnet fails at doing its job would be Ts at which the engine would be in trouble (>>300 C for the cheap magnets; higher for better magnets). I think that's what he is referring to.

 

Dude really??? This is the funnest thing I have heard since the long time belief about placing the Modern day "plastic" cased battery on the ground causes it to discharge?:lol:



And so it is that if you drive in the opposite polarity of North and South that this will also effect a magnets power as well. Cutting fine hairs on this thing about magnets. :lol:
"magnetization can relax to it's equilibrium value from the 'wrong' direction"

The word we have today is called:

Coercivity

I knew that all those science classes would pay off eventually! :lol:

Oh and I guess we had better all NEVER buy and drive an electric motor based Hybrid vehicle. :lol:

I am laughing about all this concern about the performance level of magnets so please do not take me to serious!:cornut:

 

Umm...The person did say "ordinary magnet" and such a magnet does lose some of its magnetization as temps increase. Please look up Curie temperature (Tc) or Curie point. Granted the terminal point where a ferromagnetic or a ferrimagnetic material becomes paramagnetic is way beyond a temperature our engines will ever see but there is some fall off as the temperature rises.

 

Nice find Nathan!
