i have a question to ask you fellas.
my car recently eats gas like crazy. i usually fill it up once a week. but this week i had to fill it up three times. i did drive a little more than usual, but i think this is crazy. could this be because it's the time to replace my filter for CAI? if so...can i just use any filter? or does it have to be Injen's?
help please. thankx

 

I have read that breathing mods will eventually make your engine run more rich (ECU feedback control) to compensate for the extra air if you don't get your ECU properly tuned.
