Hello
I am thinking about addind some mods to my car but I dont know what to add first if anything at all. What would benefit my car the most for the least amount of money? Also what does the cold-air intake do for the car? (how much hp increase? decrease gas mileage?)

Thanks everyone

 

It intakes cold air.

HAHA.....

AEM - $213.95
Injen - $113.96 (black) - 132.96 (chrome)

 

Okay great... Now that I am as knowledgable as possible on what a cold air intake does... What type of hp do you add from this?

Thanks

 

I believe it's like 5hp or something. I don't have it on my car, but I read it a few times on other posts. Try doing a search for 'cai' I'm sure you'll find tons of info on it. Good luck.

 

The stock intake does the job but is restrictive somewhat and satisfies the factory need for low noise. I'd go with a cold air intake as you'll get more power there as opposed to a short intake which takes in heated underhood air. This may not be a big deal in the wintertime but in summer you want to find the coolest air you can. Cool air is denser and your computer reads this and adds more fuel, hence more power. Plus as most guys here will admit, when you hit VTEC with an intake it sounds great. Otherwise for the most part you don't even know it is there. Next get the RES mod coming out and you'll be happy.

 

CAI brings in cool air and may add up to 5 hp in the high RPM range. Also adds a lot of noise. You may want to save your money and just drop in a K&N or Comptech filter.

A few differences of opinion on whether the CAI adds anything or not. I elected to just do the drop in filter route.

 

Hey, you stole my reply!!!

 

yeah, what he said.

 

The main thing CIA allows is more efficient compression. In compression theory, the colder the air the more efficient the compressor. So, less work is absorbed in commpression, thus more work is able to be transfered to the drive shaft. That allows more power when gas is full throttle and bettter MPG in normal conditions.

Just thought I would more fully annswer the question, if that was the type of explaination you were looking for. Plus I am a mechanical engineer, I always give technical responses.

 

Doesnt it give you more torque down low. If you want a nice sound, get yourself the HKS exhaust. My friend has that on his Type S and it sounds amazing. When he revs it, i swear it sounds like a mini ferrari. Its nuts. Its nice and low with no droning at highway speeds. But once you gun it, the sound is no joke.

 

Nice Car. I like the rims what kind are they?

 

Don't listen to him. The CIA has nothing to do with it unless you
want to install a RPG.

 

Holy crap...do none of you guys know what this is? Scole and chuckstl were the only ones who were close...and it's not compression theory scole, it's density. The CAI works because the air under the hood is heated by the engine, but being able to pull air from under the front bumper is much cooler. The CAI adds from 5-15 HP. I've seen a 14 hp dyno increase...actually a few.

"CAI brings in cool air and may add up to 5 hp in the high RPM range. Also adds a lot of noise. "
5-15 HP, and not a lot of noise...there is a more throaty rumble at vtec, and a little more idle noise but not much. IMHO, and in the opinions of others on the forum with intakes, the noise all by itself is a plus.

"The stock intake does the job but is restrictive somewhat and satisfies the factory need for low noise."
The stock airbox and resonator are not altogether too restrictive. The main gain in HP is due to taking in colder air. Take the resonator out alone and see for yourself.

Hope that helps,

when the resornator is taken out, you are getting the same cold air that the "Injen" and "AEM" CAI's get. You add a high-flow filter and is the same as the CAI but just $60

 

Austin, I was explaining why there was HP gains, not how CIA is able to get cold air. Yes the reason it can get cold air is because the cooler air is more dense, thus it resides at the bottom of the compartment. The part on compression theory speaks to how cold air increases HP, not how cold air gets to the engine. And, yes this is the reasons there are gains in HP and MPG. It takes less work to compress the cooler denser air. Everyone else did a fine job of explaining how the CIA intakes colder air, but no one explained why cold air helps HP and MPG.

I thought it was clear what I was discussing. I guess I assumed everyone knew the sequence in a 4 stoke engine. I guess not. Stroke 1 = intake (air comes in (cold air in this case)), stroke 2 = COMPRESSION (air is compressed and fuel is added), stroke 3 = expansion (mixture is ignited and piston is forced down), and stroke 4 equals exhaust (valves open and piston pushes gases out).

I think you misunderstood my post. It's cool though.

 

scole:
I'll shut up now I read it wrong
