The reason my MAF housing cracked and broke was not due to overtightening the filter, as it was with others. The "hump" hose that connects the aluminum intake tube to the MAF was VERY tight, and I applied pressure to the filter-end MAF flange with my hand while trying to fit the two pieces together. This weakend the flange, and eventually it cracked after the filter was fitted.
Since I've replaced the MAF housing (more carefully), I have had zero issues--no damage to the MAF housing and no loosening of the filter.
