Semi back from a very needed hiatus...Things are extremely busy still so my presence will nto be full force but I felt I owed people my thoughts on this.

IMHO the build quality on this piece was very good. It appeared to be a single piece of polymer that was then machined. This technique is widely used as it will provide a flat durable piece with no seams.
I actually cut on of these up and tested it for the K value. I had at one time posted all the graphs but apparently they didn't take (may have been when my photos were whiped for not being of my car as they were all technical graphs). I have since then gone back over all my notes (1200+ pages from over a year) and have been unable to find the exact numbers. What I can tell you is that it was a very good thermal insulator and as such will accomplish the job it was intended for.
Now to address the possible sealing issues. Actually one of the first things I told the guys at Hondata is that the gasket should have instructions to seal it to the head with a thin layer of 700F silicone. This will not only prevent leaks but will also add to the heat resistance. Of course this should be used on the manifold side also.
Now people have said that your intake manifold will always be hot because of underhood temps are somewhat correct. First I have always been a proponent of correctly vented hoods. If you have a correctly vented hood this will not be a huge problem as your underhood temps will be considerably cooler. Also what needs to be remembered is that only a certain ammount of energy can be transfered from the air under the hood to the manifold. This ammount is much much lower than the ammount of thermal energy that is transfered through a metal/graphite gasket. Because of this I do believe that you will have less thermal energy transfer to the intake charge.
This is a good investment...especially if you are a tinkerer. The gasket if properly sealed is reusable and in that sense will pay for itself after a few removals of the intake manifold.
would I buy one? Deffinately. Don't get me wrong this gasket isn't going to give you 50 hp...it probably won't even give you 1hp directly but if the ic and the rest of your turbo system are correctly working this could save you 2-5 degrees in intake charge. This may not seem like a lot in density and it really isn't but it may let you run .5 degrees more timing and get just a little more power. At worst you have a reusable gasket for 60 bucks that will give you a little extra assurance as intake temp lowering IMHO is one of the best things you can do for your car.
