This will create a nice amount of friction between the two pieces that would allow you to run the clamp down snugly, but not overtighten it. If that didn't work, I was considering using a strip of 200 grit sandpaper instead. Same concept, just glue it to the inside of the mouth of the filter, or around the edge of the MAF housing to increase friction.
That could possibly work. Thanks for the suggestion.

In my experience, the overtightening can be avoided, and yet still get a good seal and retention with the current setup. Just tighten the filter until friction will not allow you to rotate it by hand, then give the clamp screw another 1/4-1/2 turn. It will seem by the force required to turn the clamp screw that it's not tight enough (and thus why we tend to overtighten I think), but it has worked very well for me.
