And is listed in the specs
Looks like the Holley is an approved replacement part/throttle body

This is most likely so they can run a cable driven throttle body and not a drive by wire.

No. Only those engines where the replacement TB is allowed. It is a replacement for the OEM Bosch 12570790 TB in 2005-08 and the OEM Bosch 12605109 TB in 2010. The Holley part number is 860008-1.
