I have varefy that myself when I sealed off the rear of the engine bay hood [...better aero...] and took the hose off of the above exhaust hot air collector and stuffed it into the corner of the engine bay on a hot [30*C] summer day and the intake air temp on the scanguage only dropped a few [less the 5*C] degrees. I did this because I emagined that the intake air was getting to hot. Winters here get down to minus 20*C or colder so during cold weather WAI may still provide a FE benefit.  |
I only want to add that I also ran a test of a WAI, a version of my current, and found it worked:
