If you don't have the dremel or a hacksaw, or the funds to get the correct bit set I have in the past been able to get the edge of small cold chisel (or a flat screwdriver you don't care about) on the post in the middle of the torx bolt and gently pop it bending it to one side. Don't beat it like it owes you money, just a few taps from a hammer and it should bend enough to be grabbed with a pair of needle nose pliers, worked back and forth and popped off. Then just use a standard torx bit to remove it.
I take no responsibility for a bad MAF, lol.... just sayin.
