Anyone know the size of this, its the star shaped thing with a little nipple in the middle.

Went to install an intake didnt have the right bit to take this out on top that it had nipple in the middle..its two bolts holding in the MAF on each side? thanks

 

sitting in my garage with a glass of Caol Ila scotch and double checked that it is a T-10 torx bit. Easy R&R.

It's a TAMPER PROOF Torx bit, generally T20 (at least that's what K&N claims it to be). The little nipple in the middle is what makes it tamper-proof.

Here's the tool you need to remove it: http://www.sears.com/shc/s/p_10153_12605_00942617000P
