Hot & Cold air

[toyotamodus]

Dear Forummers,

I have little knowledge about cars. I do have a question regarding air intake. Hope some of you experts out there could enlighten a little. :wavey:

I read that Cold air intake is, as the name implies, taking cooler air into the air duct so as to get more boost due to a higher concentration of O2.

I also read that Warm air intake will also get more boost as the throttle is opened wider to compensate for detected low O2 level.

So, I guess you know where i am coming from? Seems like both ways achieve the same? If warm air having less o2 will lead to the ecu opening up the throttle wider (automatically), why is there a need for cold air intake? Is it better or efficient?

Any advice will be very much appreciated.


best regards

I have never heard of Warm Air Intake can lead to boost as well as ecu controlling your throttle will be automatically opened wider if O2 level increase. If that is real i think alot of people will be having accident hahahaha..Mind to share where u read or get that information from?

The colder the air, the more denser the oxygen level. the higher level of oxygen you will have better combustion, hence more power. CAI is just some design of the intake to get cold air so your car can get constant cold air for more power. No rocket Science in that.

And how do you channel WARM air to your intake system ??

Hello Evo5755,

thanks for your answers. I got the warm air intake info from this link :

Bump: I am not sure but guess its the air heated by the engine ?

Bump: I am not sure but guess its the air heated by the engine ? that is with the cold air ram intake pipe removed?

I think the warm air intake mainly apply for when engine is cool.
With warm air intake, engine can reach normal working temperature in the short time to acheive FC efficency.

Thanks to all who have contributed to the discussion.
I get a better understanding now.

Cheers!
