A 2-3 gram Nd magnet can pull 1k* it's own weight Hard drive magnets are stupid strong. Most can hold through your hand.

Bosch filters will have country of origin on the filter just like any other the ones sold there come from Korean/Malaysian and will have a crimps on the gasket. I have no real conclusion on how they come wrapped from the factory most I have seen have just plastic at the bottom which is more of what you see out of China but it could be how they are made.


i settled down with the speaker magnet since i can't really find a hardrive magnet....i'll just renew it once i change the filter and oil again. i still have 3 in stock....

as per the bosch filter i installed on my truck, they were only wrapped at the bottom with a plastic. not fully wrapped. i can't remember if they have gasket crimps but they were made in korea, it says for the oil filter. as per the bosch fuel filter, it says made in malaysia....there's not even a trace of misspelled words on the carton packaging. yes, i do check also the english construction on the instructional labels of filters and their packaging. may not be a fool-proof check though i suppose..
