Gas mileage with gen III intake

kannibul

Not the case if you're running rich, as documented....

The Gen3 intake helps lean the A/F Ratio a bit, which in turn DOES add HP and lead to a bit better efficiency, which translates into a bit better MPG.

If the A/F ratio was the same, then you (and modshack) would be correct. You can't generate HP without increasing air AND fuel. Technically, we have too much fuel going in, which in effect causes us to lose power. The G3 intake is such that it lets more air in than the stock intake, and the positioning of the MAF sensor doesn't see the additional air flow (or as much of the improved air flow)...

Resulting in a leaning effect, which in turn does give a bit better efficency/MPG.


There's that's 2 ways to explain the same point!
