I think the concern here is a turbo car so the air will be heated coming into the intake. From what I have read air temp should be no more than 180 degrees. Yes the turbo will be on the other side of the head.
Yeah but even if the air going through the manifold is 180* the manifold won't be much, if any, hotter than that. Especially with thin aluminum like that, it won't be able to hold much heat with that much air moving through it. You don't have the mass like a cast aluminum intake does to retain heat. And 180* sure as heck isn't going to boil brake fluid, even if the manifold was touching the m/c, which it isn't.
Plus the air might not even be that hot. Yes, the turbo gets hot and heats up the charge air, but with the intercooler you've got it may not even stay that hot most of the time.
The only thing I don't like about the intake is the square main body. Seems like it would create dead space near the corners.
