Fascinating, thanks for the links. Regarding Neo Magnets - just ordered a pair for my bikes. N-52 spec
"Regarding the temperature range of Neo magnets for use on our oil filters. Some of the higher quality Neo has a significantly higher temperature operating range, so keep an eye open for those magnets. As with engine oils, there are Neo's and then there are Neo's.
The magnetic field will reduce with elevated temps but the field is always there to some degree. Additionally, the metal surface of the oil filter can where the Neo is attached to will become magnetized by the Neo creating an excellent force field area. Once particles begin to collect in the area, they too become magnetized, enlarging the field area. With elevated temps the "reach" of the magnet decreases but does not turn off like a light switch. And as the oil is cooled, the magnet force field returns back to original levels. I have examined hundreds of oil filters that had Neo on their surfaces and in every case there is ferrous residue ranging from a small amount of paste to paste/chunks/clunks. i.e. there is always "something" there and that "something" is iron and steel. Any abrasives, especially ferrous, we can capture from the system is a win/win for our engine and transmission.
