All the mileage gains were lost, as soon as I put an exhaust system on it though. But at 5 mpg, the intake could have paid for itself, had I not gotten the exhaust.
I suppose it takes a careful foot not to undo any economy gains from the intake by driving more aggressively because your car sounds/feels different now.
I have yet to see actual hard data (spreadsheets, etc.) from a V owner actually pointing to a mileage gain from a CAI. I'm considering getting one and tracking mileage on two separate spreadsheets to provide said hard data that we can later point to.
But I have more pressing things to buy with that money. Like TPMS sensors and tires.
