Well, I finally got around to removing the old, crumbling hood insulation that came on my 951, removing the glue and fitting the new OE insulation pads.
Washed the car yesterday and followed the handy advice of using the vacuum at the car wash to remove all of the old insulation foam down to the glue:

Then came the hard part. Removing the glue! I cut one open one of the bags the OE insulation panels came in and used that to cover the engine. This is a must, because the mess is considerable.
Doused the whole surface with WD-40 to soften up the adhesive, but like I feared, that was not going to be enough to get the glue off. Using a plastic kitchen spoon, it took some proper adhesive remover, scraping the surface and alternating with a citrus degreaser to get the gobs of glue off. It's pretty tedious and takes lots of elbow grease, as I expected.
The best way to do it is to work in sections. I started on one side and did half a panel at a time. I found the adhesive remover worked best applying it with a rag, then scraping with the plastic spoon, and then using paper towels with the degreaser to clean off the gobs of glue.
Here's the the clean surface:

The trickiest part, however, was fitting the adhesive pads with the hood on the car, since you only get one shot at it. Made a small tear right above the washer tank, but the overall result is 100 times better than what I had before.

If you haven't done this yet or are putting it off, it really is worth it. I took my time and spent nearly 4 hours doing it but I'm quite satisfied with the result.
It's stated throughout the 944 forum archives that you can do without the hood insulation because the factory did away with it on the late cars. Apparently, however, this was only the case on North American cars through 1989, as my 1991 RoW 951 had insulation and I've seen other '91 cars with it as well.
I think you can probably do without it on a NA car, but I would definitely use hood insulation on a Turbo. My 1990 S2 is US spec and came without it, however, over the years paint on the hood has faded somewhat, while the paint on my 951 is still very thick and glossy. YMMV

If I had to do it again, I would have someone help me fit the new pads. Doing everything solo has its shortcomings!

Luis,
There is a thread in here somewhere with a guy who has a 1/4 porsche shield decal for his overflow tank. Looks OK, but, hey, everyone I've ever seen is brown

I purchased a set of hood insulation pads from Perry951 here about 3 or 4 years ago...when I still had my NA. Thankfully I never installed them (NA was sold) and they're in the box on one of my workbenches in the basement.
I am considering installing them on my S2.....nice write-up Luis!! Will be a big help if I do the install !

My PO replaced mine 2 or 3 years ago and I'm still finding pieces from the old one around the engine bay. I remember there was hardly any left on my old car. Replacing these is for sure one way to make it look nicer when you open the hood.
