MAF problem with 156 again

ok so as everyone knows already MAF is a big problem with the 156. i already changed it once about a year ago and now it is kaput again. i pulled it out and the little mirror on the MAF looks extremly scatched. i checked the piping and its all done correctly but i saw that on the top of the filter box where the 3 screws are one of the parts that go under the screw was broken so the top cover of the box is kinda not completly airtight. the i dont see how that could be a problem because the whole system has a hose going inside the filter. i also use K&N sports filter. i was wondering if anyone has any idea what coul be destroying my maf. also the MAF looked really greasy and full of dirt inside the little mirror. i am going to attach a picture to show you. you can sort of see the dirt. i tried cleaning it with isoprophyalcohol 3 times and its still there. plus its full of tiny scratches. thanks guys.
