Intake air temperature sensor
Tightening procedure
GM does not publish a discrete torque value for this item in the fastener specifications. See the notes below for how it is serviced.
Notes
The LS3 has no separate IAT (intake air temperature) sensor with its own torque spec — the IAT element is integrated into the mass airflow sensor 15865791 (callout 8 of figure 1Y03-111, 2011 GM Professional Parts Catalog: "SENSOR,MASS AIRFLOW(W/INT AIR TEMP SEN)(ACDelco #213-4222)"). The MAF assembly clamps into the air cleaner duct without a discrete torque-spec fastener. For torque on the MAF mounting screws/clamps, see the Air Intake System service procedure. This entry is retained for catalog completeness but has no LS3-specific torque value.
