You can Select Your Vehicle to check if 12614717 fits your vehicle.

The Intake Manifold Temperature Sensor is on the right side of the air charge cooler cover towards the front. First, remove cable from the negative battery terminal. Then, take off the engine cover. Next, disconnect electrical connector from Intake Manifold Temperature Sensor on the right side of charge air cooler cover. Then, disconnect electrical connector from Intake Manifold Temperature Sensor. Then unscrew sensor from charge air cooler cover. The sensor should be installed and torqued down. Finally, finish installation by reversing the procedure used to remove it.

For 5.7L (LS1 and LS6) and 6.0L (LS2) engines, remove the electrical connector from the MAF/IMT sensor. Break loose the clamps on the intake air ducts and those of MAF sensors-to-air filter housings. The intake air duct is separated from the throttle body as well as MAF/IMT sensor, after which the latter is removed from air filter housing. Reinstall everything as it was during disassembly. Tighten them firmly. It should also be noted that on supercharged 6.2L (LS9) engines, the Intake Manifold Temperature Sensor is a separate sensor mounted on the charge air cooler; while for other models, the Mass Air Flow (MAF) sensor is located on the side of the intake air duct portion of the air filter housing. Remove electrical connector to MAF/IMT sensor. Remove fasteners by unscrewing them, then detach this device from your car's air intake duct. Reinstallation follows removal steps in reverse.
