gas mileage worse after chrome intakes., i thought it was supposed to get better? Options

[Tech9ine]

hey,
I installed this chrome intakes ram air on my ST a few months ago and since I've installed it I've gotten about 100km/tank less than i used to with my stock intake. Was I wrong in thinking the gas mileage would get better if not stay the same? could i have possibly done something wrong? (it's pretty simple, i don't think i goofed on anything.)

if your logic was good, every car would get extremely good mileage in winter. But its quite the very opposite, it drops buy almost 25% +

How do you figure? It has been proven by many companies (including K&N) and I will even say that my CAI has improved gas mileage. It allows cooler, denser air into the combustion chamber. It is more efficient than short ram, because short ram sucks in the hot air right underneath the hood, which is less dense, yielding little to no gain over factory air box.

Perhaps it then uses more gas as it can burn more of it with the colder denser air to make more power though? Dunno, just guessing.
