I really don't think that intake is going to get that hot. Definitely not hot enough to boil brake fluid.
This isn't a v8 with the intake sitting right over the top of the engine. The exhaust is on the other side of the head, there's a good runner distance separating the main body of the intake from the head, and everything is aluminum (including the head!) with good air space all around it. Just look at the surface area of the intake in contact with the head and compare that to a small block intake, there's a big difference. The runners on my Eddy AirGap don't even get that hot, and it's still sitting right over the top of the engine, collecting all of that heat.
