The foam is there to not only insulate noise, but to keep the top of your engine hot to keep the egr cooler and egr and intake hot enough to allow the oil blowby to not collect and burn off.
my word, yes. My overhead map light went completely out after that video,
If anyones map light flickers at all, go get it warranteed now! that dang madule is $225 without all the addin modules.
Im actually going to wire in a replacement led light in the oem place. I don't know if it will work,
I made the video not to complain, or wine about all the problems, but to make owners aware of all the problems and good things about the truck so they know what to have fixed right away, or to prevent having issues.
