Talos have you tried header air for keeping warm in the winter? I really don't believe in EGR or warm air having more of a benefit over keeping a prius warmer so it can run like a normal corolla would without having to have the engine on 24/7 like a corolla would.

I think manufacturers dyno their cars at 77F so I usually just aim for around this temp for winter air for my car. If you go too crazy I wouldn't want to deal with the horsepower loss.

Also, WAI for me is just helpful for around town. The car does fine at steady state, but that can be a very small percentage of my driving a lot of the time.
