Magnet For Your Oil Filter...Good For Your Engine

[RX-8888]

As an oil filter will only catch particles 20-30 microns or above, anything below this just circulates around the engine...which equals WEAR!..

For those who don\'t know Mazda in the 09 RX-8\'s (R3 for UK) re-introduced a Sump Pan magnet (inside the pan), which they last used in the FC RX-7 (same magnet). Mazda Part # F401-17-121.

I can only come to the conclusion that Metal Particles smaller than the thickness of your hair is doing damage to the RENESIS, otherwise why did Mazda re-introduce an internal sump magnet for 09\'s after an absence of 10 Years without one in ALL FD RX-7\'s and 04-08 RX-8\'s?

So I can recommend the following product...

http://www.shopfiltermag.com/     US Site..OR..
http://www.filtermag.co.uk/    UK Site/Supplier.

The SS250 Magnetic Filter to be exact....have a look at the site...you can purchase one direct or from a well known Auction site..

They are simple to install and reusable for life.

I have also order one so I can have double the Magnetic catching of metal Particles.

You can also use the STRONG Magnets that are used inside ANY old PC Hard drive, Pull one apart and you will see the two magnets inside, they are FLAT though, but should still hold on the oil filter\'s metal case.

FilterMag use Neodymium type magnets or some call them "Rare Earth Magnets".

DO NOT USE FRIDGE MAGNETS OF ANY KIND, ONE THEY COULD FALL OFF AND TWO THEY ARE NOT STRONG ENOUGH.

If cheap or weak magnet(s) fall off they will allow any caught metal particles to suddenly escape into your oil stream in one large hit...not good one would think.

I recently did an oil change & rang up my local garage RE:Worx to ask if it is worth installing a magnetic sump plug but they turned around & said that is pointless as the only metal particles that would be in your oil copper??

Im a big believer in magnets in the oil system.
I do a lot of oil changes about 50% with a sump plug magnet have metal sludge on them about the size of a marble.

Really, As my original post said, why did Mazda after 10 years add an internal sump Magnet to All 09 RX-8\'s (R3)?...
Ultra fine metal particles come off your Cast Iron side housings which can end up in the oil. Plus metal wearing off your two steel oil pump rotors and shaft, and from eccentric shaft journals.

I guess it one of those things that wouldn\'t do any harm by putting one in and could do some good

To be honest i agree with you, hence why i was looking into putting a magnet into the oil system some where but mearly rang up RE:Worx to ask about it & thats what they told me was very shocked whem they said that about it anyway gonna be seeing Chris who works there soon so i\'ll ask him again about it & see what he has to say about it.

I also have one of these in my FD and every oil change I notice a small marble sized piece of gunk, surely it must be a good thing if the magent is catching it?

Thanks for the info :cheers

Sounds like it wouldnt do any harm.  Any idea what one you would need for an FD?

Good advise, I can see a lot of us doing this with our FDs, group buy?!

Sounds a good plan to me ... in fact group buy fd\'s and \'8s

Ive never been keen on this because all the small metalic particles which stick to the magnet would in turn become magnetic too. So when your next running high revs and the oil pump is at full chat, go over a bump and release a lump of magnetic swarf to stick and stay in the engine, and wont come out when you drain the oil next. How about letting the car tick over with a magnet on the filter for five minutes before the oil change, best of both worlds?. This with regular changes would be your best bet?:wiggle

anyone know which one would be suitable for the FD?

[Initial-D]

If there is this risk then why would Mazda run them on the RX-8?
