I'm thinking about getting an Cold Air Intake. I have a couple of questions.

So far, I know that it's suppose to boost your hp by a tiny bit, make louder noise, and makes your engine area look awesome.

My friend here is telling me, that the engine works like a computer and, Cold Air Intake keeps it cold so it'll perform better.

So that would mean, there are absolutely no side effects to using a cold air intake? It won't shorten the life of an engine but infact make it longer?

What does Cold Air Intake actually do technically?

OMG. Your about to start a debate that will go on forever. Technically that's kinda correct but there are things that can go wrong. I won't get into just yet. I want to see what everyone else is going to say B 4 I open my mouth.

Colder air is more dense. Therefore contains more oxygen. More oxygen = more horsepower

For more about oxygen and HP see Nitrous Oxide

Bwuahahaha! If I cool my engine enough, maybe I can overclock it more! Hehehe, but seriously...cooler air is is denser than hot air. Therefore you'll have more oxygen available for the engine to burn.

if you really wanna learn how it works check out www.howstuffworks.com

learn how an engine works first and then you'll understand why the dense air helps combustion

nonononono............NO!!!!!!!!!!!!!!!!!!!!!!!!

u got it all wrong.. cai sucks in more dense air... meaning it burns more fuell.. meaning less mileage.. meaning about 3mph boost when u speed..... also u have chance of sucking in water and foooocking up ur engine....

it doesn't cool down the engine at all.. in fact it makes it hotter due to the higher combustion rate in the engine... n it does shorten the life of engine.........

a car is not like a computer.. a computer can last for a long time. but an engine can't!.... u can't just put a heat sink on the engine.... the engine has life strain to kill it.....itz the strain man...

if you were a boy scout or wat not, you know that for fire, you need air.. air=oxygen. and if you know your basic science, cold gas has more density than hot gases. so put those 2 together.. cold air(more oxygen)+fuel for combustion(more oxygen from colder air)=better combution than using hot air.

More air(colder air) = higher compression = more HP

Just go for it. Don't drive through any deep puddles though.

the combustion in the engine is always going to be hot no matter what. we arent saying it cools down the engine. the increased denser air flow does mix with fuel and gives it a higher combustion rate thus creating more power. also the reason why you reset your ECU after you install the CAI is because the ECU needs to adjust itself to balance out the air/fuel ratio.

exactly! that's what i was trying to say! yeah! but yea that's true but yea! right!

so how's the lakers?

so is SRI any good? i know SRI doesnt have the long pipe like the CAI that extends all the way to the front bumper to suck more cold air
but would the SRI suck more HOT air into the engine? i am little confused about SRI vs CAI
can someone post pics of both? thanks

ya the sri sucks hot air because it sits right next to the engine

honestly - unless you floor it through a puddle you're fine. and also dont get the intake thinking it will be this huge increase in power cause its not. to get the most out of your bolt-ons (ie.intake, header, exhuast) you need to follow Spider883's lead and do the port and polish. sorry but increasing airflow into factory restricted engine isnt gonna do much

If you don't know what a CAI does, I say you are best not getting one.

oh yeah, i just wanted to add that I did not mean my last post as a "flame" or an "insult"; I was being serious. I know everything about every part I've put on my car, and that's the way it should be.

I don't know if this is the case, but in terms of true HP gains, the whole I/H/E setup is not going to do much - I debated it with a mechanic that's been working on Hondas for 20 years. His opinion on the whole thing was it's the first step to making more HP - basically by getting rid of some of the restrictions from intake to exhaust. But there's only so much you can squeeze out of the engine without port and polishing - after all, as he said, there's a certain point to which you can squeeze into the combustion chambers, and then no more...but it;s good to do anyhow!

So then how is he supposed to learn about this stuff if he does'nt try it out.

does the ECU have to be rest after installing the CAI...or will the ECU learn and adjust itself...

Thanx

you should reset it by disconnecting the battery

Or just take out two fuses in your under-hood fuse box(FI ECU & backup). That's how I do mine.

Come on, there was a time we all didn't know what it does.

Your ECU will eventually figure it out from lean readings from the O2 sensor, but it will take a few miles of driving. You are better off from a MPG/performance standpoint if you just reset it immediatly

Iamfob: the difference between a sri and a cai is that an sri sits right next to the engine so it is sucking up all the hot air from the engine bay, the cai extends all the way down behind the front bumper and next to the wheel well therefore the air that a cai is sucking in is going to be much cooler cuz it is coming from the front of the car and not the engine bay, hence you will get more hp gains out of a cai because of the more dense air......just watch out for the puddles!![IMG]i/expressions/face-icon-small-wink.gif[/IMG]......but nothin that a little air bypass valve cant fix

Okay here is the deal the factory air box is very restrictive because that is the way honda designed it. A Short Ram Intake will let air flow much more freely for an example if you try to suck air through the stock air box wil your lungs it is very hard but if you do the same thing with an after-market SRI it is much easier. The resonator provides alot of resistance.

Now to move onto the Cold Air Intake. As eveyone knows the engine requires 2 things to create power, Fuel and Oxygen. The colder the air the denser it is and the more oxygen there is in it. CAI also are less restrictive then the stock air box.

Because you are able to get more oxygen into the butterfly the ecu sends more fuel so as not to make the engine run lean and in the same stroke of the engine there is more fuel burned and more power made. This is the same reason n20 is so effective n20 has a higher level of o2 then regular air

for CAI: i know there's AEM and Ingen, any other brand?
for SRI: i dont know who make them, anyone know? and how much difference between the two?

Guys sorry...but I can let this thread keep growing.......just Search "SRI"...and "CAI"..and all your questions will be answered....-LOCKED-
