Some early 2006 Chevrolet Corvette Z06 air induction system MAF sensors were attached to the air induction housing with five-lobed Torx Plus tamper-resistant fasteners.
These fasteners have a post in the center of the lobes.

If it becomes necessary to remove the MAF sensor and you don't have the appropriate removal tool, use a thin cut-off wheel on a die grinder to create a slot in the fastener head.

TIP: The air induction housing must be removed from the vehicle before grinding.

Once the slot is cut, use a straight blade screwdriver to remove each fastener.

GM p/n 11589093 is available as a replacement fastener. This service fastener has a T20 Torx head.
