It seems to me there are a lot of mistakes in understanding on this round of mods from them. A larger contact patch will have greater rolling resistance than a smaller contact patch. And a HAI/WAI does not leanout the fuel mix, which the ECU will keep at stoich by reducing fuel,but will instead reduce air pumping losses through the throttle by requiring a wider-open throttle to achieve the same power. Last, whatever happens to swirl air in the intake tube is not relevant since all that air is about to be dragged through a filter.

They should see benefits, but their explanations about why will be wrong, if what I have learned here and thruogh other reading these last three years is correct.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
