I just purchased the magnus heat barrier intake manifold gasket for my 2nd gen gst. Its made of a hard plastic. I have heard that people are having trouble with them leaking. Some say that they use a stock gasket on the head then the magnus gasket, some said they just used the magnus gasket and some said they used a OEM gasket/magnus gasket/then another OEM gasket. Some have used RVT sealant with it. How is this thing supposed to be installed? Do I just use the heat barrier gasket by itself?
Anyone using magnus intake manifold gasket?

Hmm good to here because I just bought one. 
I was thinking about doing what asmo said and sandwich it between two oem gaskets. I don't really want to do that though I think I'm just going to use some rtv on it and throw it in there. If it leaks I'll blow up the car.
I'm going to just unbolt my throttle body and set it back there that way I don't have to take those damn coolant lines off. Hoping to have it on Thursday so I'll report back with a boost leak test.

Reporting in with successful heat barrier gasket. I've got an ebay one, which is much thinner, and a Cyclone IM which has no EGR port at all, and so far no warping or ill effects. I love this gasket, I swear. I could make 50 pulls all at over 20lbs of boost in 96 degree weather with a heat index of over 104-107 degrees, and the gasket works so well I literally can(and have) lean on it, without even an inch of mild discomfort. This gasket rocks. If I ever..ever swap out my 1G head for my 2G head I have laying around, you best believe I'm going to purchase another one.

Cracked, did you use anything to seal it? Or did you just torque it down and call it good?

There are mixed reviews out there about it failing. I just want to hear from people with first hand experience. I have one I'm about to install and I want to make sure it seals right.

A piece of plastic that thick (Even crushed) will still move around when it gets heated. Then when it cools you wont seal properly because it will deform. Hence boost leaks.
The best bet is to use for drag racing only and monitor after every race. Another thing (What I did) is to make a 2" thick phenolic spacer on a Machine. Its like wood. This thing wont deform and holds a ton of boost. I did it to my car. Keeps the intake temp alot cooler than the block.
