Hood Insulation
Has anybody added underhood insulation to their 2017+ Super Duty? It appears that the part number is HC3Z-16738-A, and the fastener appears to be -N808842-S...are these correct? How many fasteners are required? Is there anything else required to accomplish this installation? Thank you.

Not sure, I added one to my 2004 XLT, my fear is that the added heat from the underside, in addition to the hot sun MAY have an adverse effect on the paint...

I may be wrong but I believe they are not only to protect the hood paint from chipping prematurely but also as a safety feature. They are designed to smother an engine fire in the event of one. They fall from the hood and smother the engine bay.

I've heard this also. Fire makes it fall onto the engine bay at least temporarily smothering the fire. Not sure why it's not treated like a seat belt and installed on every vehicle. I have it on my 93 Silverado as an OEM install.
