Injector heat shield

Hello Jeepers, I have an issue beyond my experience.

I am replacing the valve cover gasket on my 02 X, and as I am removing bolts, I notice a heat shield covered in greasy mud. From what I can gather it is for the injectors? It is pretty weathered and full of mud and grease. I was going on line to find the part to order a new one, but I seem to be finding write ups from other jeep sites about a recall on this item. Very vague threads, was wondering if it will harm the engine to run without it, even for short while until new one arrives. Also, is there a newer part for it that is better than the stock oem part? Just some general knowledge on this item would also help. I'm venturing out trying to fix things myself to learn about my Jeep and to save on labor costs, just don't want to cause more problems by messing something up. Thanks everyone! Here is a picture of the part...

The insulation is to help prevent heat from the engine from causing heat-soak issues in the injectors. You can safely drive without the insulation but plan on replacing it when you can.

Thanks, Jerry. I was hoping you would respond! You seem to have a lot of useful knowledge, and I thank you.
