Well dang, I never knew that! And here I went to all the trouble of making a hot air intake for MAX (Kubota-powered sports car) thinking that temperature was more significant than density on a compression-fired engine (and that reducing density would be beneficial too, because it reduces pumping effort). Why does cold air intake improve mileage on a diesel?
PS--mine's turbocharged--would that make a difference in optimum air temp for FE?
