What does a cold air intake do for a car?

Does it improve gas milage? Acceleration?

gives you more power. colder air burns better
What does a cold air intake do for a car?
yes on both i think, it cools the air thus compressing the air, this compressed air has a higher oxygen content and more explosive power when mixed with fuel and spark. So stronger engine and more efficient.
Reply:Won't improve gas mileage noticeably (maybe just a little...). Horsepower is determined by how much air/fuel mixture detonates in the combustion chamber (among other factors). Modern engines measure the air being brought into the engine, and deliver the right amount of fuel with the fuel injectors.


Cold air is more dense than hot air, so the colder the air, more air (by weight) can get into the cylinder volume. The engine senses more air, delivers more fuel. More power!
Reply:Sucks in cooler air than a regular intake. The cooler the air, the more condensed the air is which is better for your engine


(in terms of power). So pretty much it just gives you more power.
Reply:cold air intake does what it says it does it brings cooler outside air in to the engine.


cooler air has more air molecules, when ignition occurs more expanding gasses, more power


thats all they do, same as an intercooler for a turbo
Reply:it increases horsepower.





a cold air intake (CAI) will:





1. allow the engine to suck in more air due to a better (cone) shaped air filter.





2. if its true CAI and not short ram intake then the air filter will be down near the fender and the air will be cold (as opposed to warm air in the engine bay) and this will allow the air to be more dense (due to coldness) which contains more oxygen which is basically the same as getting more air.





the MAF (mass air flow) meter will tell the fuel injectors how much gasoline to add to the air depending on how much its getting in and how dense it is, and therefore your car will go faster. about 5-10HP faster.





this might give you a little better gas mileage but not much.
Reply:Cooler air is more dense than warmer air. When the air is cooler, the combustion is more complete generating more power as the fuel is burned. Unless you conscientiously drive to conserve fuel, the mileage increase is small but the horsepower gain is very noticeable.
Reply:fuel is denser at colder temperatures. Making the intake air to your engine colder in turn makes the fuel temp drop. That will produce a more complete fuel burn, better milage, response, acceleration, ect. That is why there is almost always an air cooler on a vehicle with a turbo for example, because turbo's create so much heat
Reply:It makes your wallet flatter!


Intake manifolds are heated to what ever your engine runs at on the temp gage (over 210 degrees). So even if the air is ten degrees cooler, it will be heated to 210 degrees any way.


So not-ta thing for performance or MPH.


Now a less restrictive air filter, yes that will help.


But cold air intakes (unless ram air) only make the straw longer that your engine is sucking through, and cost you money.
Reply:It just makes a sucking noise when you give it gas, buy yourself a K%26amp;N air filter that fits in your stock airbox and you will get the same results without all the noise and save yourself $100.
