Changing plugs on a 2004 XG. After removing the intake a piece of curved plastic fell out of it.I took the intake apart and for every cylinder there is a channel and butterfly. The curved plastic piece directs airflow. I assume this might have to do with cold weather starting (choke) but not sure.I cant seem to find what the part is called and cannot find it on a web search. Nearest dealer is 65miles away so its not easy to talk to the dealer.If anyone knows what I am describing where can I get one. Looked on hmaservice but couldnt see the parts.
