Replacing MAF insert... What size torx bit?

I've got a MAF sensor from ebay coming in the mail. Instead of getting the whole thing, I just got the insert. I know its held in there by 2 torx screws. Anyone know what size torx bits I need to pick up to remove and replace the MAF insert?

Thanks

I purchased a set of TORX security bits at Advanced Auto Parts for $10.

Note: You need the 'security' type bit (has a hole in the center).

Might be able to buy just the required T-20 size bit at Sears or elsewhere for a couple of bucks.

Went to Sears and bought a set of 6 or 7 torx bits (with the hole) on sale for $20. They didn't have in stock just the single bit (T20). Would have been $8 for just the single bit if they had it. Just replaced the insert, the bit set is probably getting returned sometime this week.

I got a Bosch MAF insert new in the box on ebay for $95. Also saw a complete MAF sensor for the CLK320 for $65. Probably could have saved a couple bucks if I bought that and just took the insert out and put it in my 430.

Thanks for the help.
