my point exactly we use german built equipment but get our filters from the manufacturer which is in the USA. Same filter just lessens the cost of shipping it overseas and then bringing it back here. As many have stated check micron, overall quality and if possible find who makes your toyota or yale labeled filter and get it direct for less. Air filters I'd say definately stay oem or at least work with the original manufacturer. For example the mits sks engine uses a donaldson filter with a certian # on it. If you just go by the number you can miss that mits had a special designed seal on the end that is only available through mits...makes a huge difference.
