I had 3 months running the old setup and hope this improves my winter mileage. I seriously doubt I could run this in temps above 70 but will see.

When I was reading about the WAI/HAI, I never noticed a restriction on time of year. Why wouldn't it work in the summer? I can't find this restriction in the the other threads I read about. Is it a melting parts issue ?

I like your idea though, one of hte big 3 used this setup way back when on a "highway" car or something like that, they got extremely hot intake air, i'm not sure exactly why they wanted it, but they got it. I was thinking something like this for a heater on my car, suck air from around the exhaust manifolds, instant 1,000 heater, thats' gottta work better then 200 degree water. Sure if i get a leak I'd quickly die from carbon monoxide poisoning, but hey, thats' a chance i'm willing to take for a nice warm car haha.

The material is aluminum. It is actually used to do trim around vinyl siding. Its called trim coil. What worries me is the paint and hard coating on the aluminum. It will burn. I just don't know the flash point.

I'm going off cheapybob's research. He said that intake temp should not exceed 200 degrees for maximum economy. In the summertime this setup could easily get too hot and cause the ecu to pull timing and reduce economy. If I had a way to monitor this realtime I could tweak it. But since I don't I'll just stay on the safe side.
