wow... chinocharles.. everything you said makes sense... now i understand... it's all physics. by the way have you heard of the vortex air intake? it just swirls the air going towards your intake manifold... i kinda don't believe it will give you more HP as opposed to what they advertise. whatcha think man?

I've heard some real-world gains with Tornado's and related products, but it could be bullshit. I've never had one myself so I can't really vouch for it. IMHO if you're one of the people looking to stretch the gas mileage on your Yaris (I'm not that person) go drop the 15 bucks or so on a vortex generator and test it out. What do you have to lose?
As far as how it affects mileage, I don't know much about cars but I do know my math and science (physics) and I'll propose this idea and someone smarter can correct me if I am wrong, but... in the intake there is a sensor for the amount and composition (temp, speed, etc) of air coming into the engine, and according to this reading fuel is richened or... uhm... stoicized? (thinned out haha) Like I said, CAI means more oxygen which means the engine (with the MAF sensor info) will "know" it doesn't need as much fuel and will use less accordingly. I don't know a wrench from a mouse, but it makes sense to me. |

Yes exactly.I have to say that the consumption of fuel isn't affected at all.If you drive carefully, the car remains as economic as before.

So bottom line is that if you drive the same way after installing a CAI, your MPG will go down?

I don't know if it will go down, but for sure it will not go up.

but at a similar air flow the engine will see the same amount of fuel with or without a cold air system. but the colder the air, which the temp sensor should pick up, also adding more fuel to compensate for the denser/coler air? it would seem to me that with either better flow or with cooler intake temps the engine would see more fuel at a given throtle position? so you will either get a gain in power at that throtle position, or you will need less throtle to net the same power from the engine. i am no scientist or expert (or english major) but that is just the way i see it, i may be wrong, but just maybe something to think about. edit: i thought i was posibly clarifying something, but after posting, i am not sure if my original intent was reached...sorry if i confuse anyone |

Ιn order to be sure about, I just measured my fuel consumption and it was pretty much the same.
I am telling you guys, the only difference you will see, will only take place if you stop driving economically, because of the perfect sound tha CAI makes.

Know that most people will tell you a CAI is SUPPOSED to improve mileage. The difference may be negligable on a 1.5 L 4 banger, but as your engine gets larger the difference should become more noticable. |

Well said mate.
I have to say that in case anyone needs to make a CAI I am here to provide him with any useful information on it, like measurements, AFM(MAF) install etc.

I don't know... the TRD option in America looks nice because it has that built in valve to stop water intake, which frees you up to place the cone where you will see the biggest gains. You don't see that on the AEM intake that was just released, and the TRD is only 30 or 40 bucks more if you order it from trdsparks... some food for thought.

Yeah right.
But I think that the place, from where the TRD CAI takes on fresh air is not the best choice. How much does it cost? I paid 170 euros for the custom CAI.

Thats about 215 bucks... more than a hundred dollars cheaper than the TRD option here, but we all know that money spends a lot different depending on where you are. Who knows what the hell any of this means, haha.
I'm not crazy about where the cone on the TRD option sits either, but I've got some plans to free up some air... possibly cut a hole in the front bumper and throw a gromit and some mesh in there. Functional ram air sans lame-ass hood scoop. |

Here is the TRD CAI installed on my 1.5L you can see the bypass valve clearly, I have noticed a hugh difference in HP (5 or so) and about 6-7 MPG increase.... all for $350.00 USD installed, only reason I had it installed was to keep my warranty on everything.

I don't care about warranty cause every time I go for a service I just replace the old air filter box.
