WHat size are the bolts for the MAS

[Jason94sport]

I was all ready to clean it out this weekend. Then noticed the bolts were torx. I have a set of torx drivers, but they don't fit. I also noticed a little notch in the middle the prevent my drivers from working. ANy help please!

You can do a search to find this info here, but it's quick so I'll tell you that you need what's called a "SECURITY STAR TORX-20" tip and I found one at AutoZone. Ford used security star torx for their MAF housing I guess to keep people from getting in there. p.s. it really helped reduce pinging when I cleaned mine.
pps use O2 safe carb cleaner spray, make sure the can says "Safe for Oxygen Sensors"
