6.4 Jeep SRT8 Exhaust Manifolds

The part numbers you listed earlier are the same as the ones in my 2009 Grand Cherokee parts manual for the 5.7 engine, the only thing that changed is the removal of the EGR valve which happened I believe after '07. It's the only parts manual I have so I can't say anything about compatibility for other years of the WK/XK platform or other platforms.

You could take the part number to the dealer and they can look up compatibility between platforms. I did something similar for the intake temp sensor that I was looking to use from a 6.4 Challenger on my 5.7. The sensor is longer putting it in the middle of the airflow which some are claiming it increases throttle response after a heat soak. I would love to know if the 5.7 Jeep logs would work on a 5.7 in an A-Body as that is my plan and don't want to drop money on headers if I don't have to.
