the winter/summer argument is also slightly nullified by saying that colder air in winter makes for higher O2 density, thus increasing economy (hence why so many have CAI)
likely a sensor is bad/needs cleaning, so go to a shop accordingly if you don't know your sensors/how to test/clean them | By the same token that higher 02 density increases efficiency, It also increases drag on the car itself... Therefore DECREASING economy.  |

otherwise, why would you put a CAI in? its to get more power, due to higher efficiency, etc. so - taking the position that you wouldn't use the extra power, you would be more efficient, hence less fuel

I will check the O2 as well then. I just didn't want to buy and replace if it wasn't the problem. | The 02 sensor on an RSX is rather expensive (by Honda/Acura standards).
If you have basic mechanical skills and can spare an hour or three; I would suggest removing and cleaning the IACV, TB and 02 sensor with carb cleaner or gasoline. Often a significant improvement in fuel consumption can be achieved this way, and it's virtually free. If you don't see a significant improvement, I'd suspect a failing 02.

One of the ep3 people I know had a faulty o2 sensor, even though the check engine light didn't come on.
It was the first thing I suspected since it was only getting 340km per tank

With a CAI, your MAF would sense more air flow, so your car uses more fuel to compensate for that extra air.
The extra air doesn't "take the place" of fuel.
CAI = more HP. not better MPG.

it has nothing to do with airflow (that's not true, you do also get more airflow, assuming your stock system is low-flow, as most older american cars used to be, but that only helps give you MORE power)
higher O2 density in your air means more efficient burn of your fuel = more power from the same amount of fuel, vis-a-vis, less fuel used for the same performace

for a little while i was getting 11/12L / 100km (used to get 9.5/10L). Dumped in a bottle of Chevron fuel cleaner and now i'm back to 9.5/10 range.

i think ur flux capacitor needs more blinker fluid
you can get a new flux capacitor here: EB Enterprises 121G - Flux Capacitor | O'Reilly Auto Parts | |

higher O2 density in your air means more efficient burn of your fuel = more power from the same amount of fuel, vis-a-vis, less fuel used for the same performace | Are you basing this info from the box of your intake?
After the MAF, your air gets restricted by the throttle plate. So the only time you'd somewhat get "better" mileage with a CAI is when your throttle's wide open. This is how the intake manufacturers can make these claims of "better" mileage... But if you're throttle's wide open, you're likely on a highway... which you'd get better mileage on anyways.
The CAI mileage difference with city driving will be minimal. And by minimal, I mean your mileage will be slightly lower.
Sure, MAYBE even for the first week or so it might be a tad better, but ultimately your ECU will reset itself and default to "more air = more fuel."
Unless you have your system and ECU tuned along with your CAI specifically for better mileage, there is just no way a CAI alone can give you better mileage. More power, yes. But more mileage just doesn't make sense.
