I've read that an aftermarket intake such as a SRI or CAI actually helps your gas milage because it allows more air into the engine, however, my dad and others seem to believe that if your engine gets more air, it uses more gas...

Can someone please shed some light on whether intakes help or hurt your gas millage?

 

depends on which application, usually you see no mpg gains, sometimes you do because it helps with the combustion of the unburnt fuel, which results in more power. the main thing that affects your mileage is the way you drive it, whether it be aggressive or normal.

 

ok thanx ej6buddy, but would it hurt your gas milage just by putting it on?

 

i've had a sri for over a year now and have recieved better fuel economy than before it was installed. and like i said, it all depends on driving style.

 

K thanx for all the help!
