Default Intake manifold hooked to cylinder head

Next to the EGR valve, is a small rectangular plate on passenger side of intake with two small steel tubes
running into the cylinder head in a loop and won’t come loose. What is this and where or what is it for? After
soak overnight in PB Blaster it came loose.

Without seeing the car, the only thing I can think of would be a choke heater mechanism.
