intake = better gas milage?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I was wondering today if my intake or any other intake for that matter improves the gas milage? I would check myself but I have the faulty digital speedo and when that does not work my odometer doesnt work and I havnt had the speedometer working for a full tank yet so I cant tell.  I was just wondering.

Also if anyone knows how to fix the odometer so it works even when the speedometer is off. Thanks

usally your gas will decrease due to more air and more full being used.

Basic idea (works for most stuff)
anything that increases performance increases comsumption.

it only increases consumption when your using the new potential.  If you look at it from the other angle, you have just made it easier for you car to do the work it wa doing before.    So YES, when driving normally you WILL see better gas mileage.  same is true with exhausts.  If I use that new potential released by thew mod, my gas mileage drops drasticly..  when I drive normally it rewards me with a good 2-3 mpg more.

Uhhhh.... i dunnow about that one, but i could explain it from the fact that you lose power. eg, with intake and exhaust u lose low end, what actually makes your car a bit slower when u are cruising around....

It probably wont make much difference either way. Your air flow through a barely opened throttle isn't going to be affected by a filter a few feet away from it.

Theoretically, an intake would give you better gas mileage as your engine is running more efficiently due to more air entering the engine.  The reason that most people don't think it does, is they like to REV their engine so much to hear the sound of their intake! <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/biggrin.gif" border="0" valign="absmiddle" alt='

Hmm, i don't think it's really the case. I don't think that any of the better flow argument applies to the mpg. The point being that your ecu resieves data on how much was flowing through and what temperature it had. The intake improves the amount that flows through. When the ecu recieves data saying that more air is coming through, it dumps more gas. That also makes the engine smoother. Now when u put the cold air on, you lower the temperature, and again the ecu is dumping more fuel in. So the only way i see it improving the mpg is when u are cruising.... but it's reall questionable... my stats on when i had the intake were something like this:
Stock - 23.5mpg
Injen + CAI - 22.5mpg
Injen + CAI + Tornado - 21mpg
