Came across a topic regarding "Dimple" brand magnetic drain plugs, and thought that having a magnetic drain plug that was 1435x as strong as the OEM plug might not be a bad idea for both the engine oil and the final drive oil drain plugs. I have had small amounts of magnetic filings stuck to both drain plugs on the RS, and a stronger magnet would be able to pull finer particles than a weaker magnet. The cleaner your oil (especially with longer service intervals) the better the lubrication and the longer your lubricated components will last. If you intend to keep the bike for a long time (as I do) then this is cheap insurance.

At Beemer Boneyard these are:
Oil Drain Plug - BB11118530317, 20 x 1.5 mm - $29.95
Final Drive Drain Plug - BB33117705854M, 12 x 1 mm - $29.95

The prices are not too bad too, since the BMW parts are $21.64 and $20.67, respectively (MAX BMW).

There are only 4 reviews on Amazon (3 x 5 star and 1 x 1 star for customer response in 2015) where the product is presently not available. More reviews on Google.

Thoughts on this product? Any experience with them?

I pulled the plug and ordered both of these in time for my next oil changes.

1435X more magnetism? Sounds like overkill to me unless you are expecting to pick up chips big enough to read serial numbers.

Maybe it will grab nails before they get to the rear tire

Chips or nails, at least the engine should not get to grind them up, and that is a good thing.

First thing I thought about when I saw that 1435x number was the General Motors Magnetic Ride Control Technology which results in a change of viscosity of the "magnetorheological fluid" which then slows down the suspension damping action, i.e. the fluid becomes more viscous. In our engines more viscous oil results in more resistance in the engine and less power output. So the question is at least, what effect (if any) could a very strong magnet on oil viscosity?

Of course, for that effect to be realized, the magnetic particles would have to remain in suspension instead of sticking to the plug. With a passive source of magnetism (as opposed to an electromagnet in the GM suspension system) the particles are less likely to remain suspended, or else it would be failing at its job.
