Was the crack through the flange that the filter attaches to, or through the center of the housing? If it was through the center of the housing, I would blame that fact that the hole in the heat shield isn't centered properly for the MAF housing, and the housing makes constant contact with it. This is an issue that K&N is aware of, but I have no reason to believe it's been fixed yet. I have modified mine to eliminate that problem.

I mentioned this in the K&N CAI thread, but I will mention it again. It is very important that you don't overtighten the filter to the MAF housing. Tighten the clamp until the filter no longer "slips" on the housing as you try to rotate it, then turn the screw on the clamp just a bit more.
Lesson learned hahaha. Glad to hear it's only $7. I was thinking far more than that...
