There is no IAT sensor. At least not on LH2.2/LH2.4. And since the injectors are placed in the end of the manifold next to the head, the manifold will not be much cooler at all. The head and valves as well as all the other things mentioned will of course be kept cooler with E85 though.

I have seen those in action and they work remarkebly well actually. The manifold stays a lot cooler. It may be concidered a good upgrade.

This usually happens when the temperature drops. As soon as you start to give it some gas it will start to ice up around the fuel-rail and the injectors, while the turbo starts to glow. Kinda' cool if you ask me... (Many people have given their reports on this, so it is actually true)
