I installed an american muscle cold air intake about a month ago and since then i have noticed that my gas has been wasting faster than usual. Is this because of the intake,did i install it wrong or what? Or is this because you need a tuner or what? any help would be appreciated.

 

A CAI shouldn't be negatively impacting your gas mileage. Also, if you have a car pre-2005, you don't need to tune it.

 

If you didn't get a connection on tight and it has an air leak post maf it can cause problems with fuel mileage as will a sensor that you might of forgotten to install. My advice is go back over it and make sure everything is hooked up and nice and tight. Otherwise it might just be you using the throttle a bit more to hear the intake. assuming its not a 05 or later car.

 

yea i think you are right,i have been pressing the pedal more to hear the noise. I am going to take it apart and re-install it gain just to make sure,thanks.

 

I just watch the video again and i noticed that after he took the m air flow system off the stock plastic thing that he didnt use that circular filter looking thing later. i put this circular filter thing between the m air flow system and tube when i screwed them together . was i not supposed to? oh and its an 01 mustang

 

no you don't use it and you kinda defeated the purpose of this thread by saying you press the gas pedal more to hear it whistle lol..

 

oh ok and yea i know i just realized that too,lol.

 

rofl... this thread was funny made me laugh.. hahaha good job buddy.. ya I got a K&N Ram intake from AM... and I could really hear it sucking in air. lol

 

Well I guess this was solved...

If you punch the gas harder, you get less gas mileage.
