Which Intake?

Ive seen a v2 intake, cold air, short ram... whats the difference between these? How much better does one of them perform? Im thnking of getting one and i dont know which one is the best.

v2, but u can hydrolock your engine with a cold air. id suggest a icebox, google it and u will find tons of them. ram intakes suck in hot turbulent underhood air. but this has been debated to death, so some dont agree with me. but most will agree on a icebox

go cold air for more power for mid-upper rpm range. you have to be a idiot to hydrolock your engine. jersey got showered with 3 inch rain yesterday.i was fine. as long as you avoid puddles, and you dont live in an area where the rain can buildup to about 5 inches off the ground your fine. the aem intake sits right on top the passenger side water guard, so get the cold air!

i dont know about that i would never recomend a cai for a lowered vehicle..... my friend almost hydrolocked his ride at night goin over a deep puddle u couldnt even see, he was smart and shut the ignition off right away and pushed it out ... sometimes u just cant see them puddles at night so in my opinion a bypassvalve or ice box is a must if u plan on lowering it and even if u dont just for peace of mind

If you have the AEM V2 with a bypass valve it won't suck up water right?

so wut is the difference between a cold air and v2? does a v2 suck up water also just like the cold air? my car is lowered so im probably going to get a bypass valve if i do get a cold air. thnx for all ur advice.

the v2 is just a diffrent design than the reg aem cold air.

they can both suck up water unless you get a bypass valve.

if you planning on going with a reg aem cold air you should just get a generic one off of ebay unless you want the name bc that design has been copied by everyone now

U CANNOT USE A BYPASS VALVE WITH A V2 INTAKE THE TUBING IS TO BIG.. and they will both suck up water there both cai's the v2 is just bigger thats all

First of all, there are more things to consider with intakes than just the "bottom line". And another thing is that adding a bypass valve to a cold air intake makes it nothing more than a show piece because it takes away all the gains you would've gotten.

A short ram from AEM has a 3" diameter with a shorter pipe length. A cold air intake has a 2.5" pipe diameter with a longer pipe length. What does this mean? Short ram is better at high end and cold air is better for low end. Anyone that tries to tell you "cold air means it sucks in colder air from under the car" is lying, the difference in temperature is negligable. The only important feature of the cold air over the short ram is the infamous "cold air bump" that is a short jump in power at around 4k rpm.

As for the v2, dynos from AEM and import tuner show that it actually provides very little power on integras anyway. If I were you, I'd go with a short ram. It's a lot cheaper and it provides the same low end as a cold air (except for the "bump") and better high end.

I seriously doubt that it true. Why the heck would AEM design a bypass valve that completely negates all the advantages of getting their CAI in the first place? Does that make sense to anyone?
Now, my personal opinion, the risk of sucking up water with a CAI is overblown. I had a AEM CAI in my GSR for 3 years and 30K miles, never sucked up water. And I had a few instances where I thought I might, really big puddles. I'm in N.H. too, plenty of rain to go around up here. The part of the pass. side wheel well lining that extends forward to the front bumper protects the filter really well from keeping any large amount of water from hitting it. If you've installed one you know what I mean. You would need to hit and VERY LARGE, DEEP puddle at HIGH SPEED to get enough water to the filter where it may suck it through the filter and to the engine. As long as you have a pass. side wheel well liner that you put back in correctly (not missing a bunch of fasteners and just flapping around under there) after installing the CAI, don't worry about water.

"Short ram is better at high end and cold air is better for low end. "

That's true, but this isn't 100% accurate....

"Anyone that tries to tell you "cold air means it sucks in colder air from under the car" is lying, the difference in temperature is negligable.

When the car isn't moving, the air behind the pass. side corner lens IS going to be colder than under the hood. Once the car is moving, the air temperature in these two locations is indeed negligible. That cooler air at launch/low speed, the piping size being smaller and the 4K rpm "hump" are the reasons CAI is better than a SRI for low end/midrange. SRI's are better for high end because underhood temperature vs. front bumper temperature are virtually the same at constant speed, and because the larger diameter, shorter legnth piping of the SRI allows for better throttle response and a larger volume of air to be drawn into the TB at high rpm vs. the longer, thinner piping of a CAI.
When your engines screaming at over 6,000 rpm, it's gonna want to be sucking air through a short fat straw, not a long skinny one, to get all the air it can to keep creating power as rpm's climb and airflow speed and quantity demand increases. But when it's just sipping air a idle/low rpm's, the long thin straw works best.

Launching/low speeds, there are temperature differences, sorry I overlooked that.

As for the bypass valve, that's just what I've heard from TI. I would guess that it would eliminate most of the gains at least and as you said, it's not as important as everyone makes it out to be.

I think the bottom line is that if you just want better drivability, go with the CAI, if you want to really build up your high end the go with the SRI. As far as I'm concerned, the v2 is a trickier puzzle to crack. Like stepped headers, this intake has two different diameters so in theory it should have the best of both worlds (since it's also not quite as long as the CAI). I don't know if I would cough up the extra $ for it though. Made 20hp and 18ft/lb on a type-s though *shrugs*.

If you're going to shell out the dough for a V2, you could consider passwordjdms carbon fiber short ram.LINK

thats the same intake ^^^ that i have on my teg. That bitch is loud when im floorin' it. I love it.

Looks sweet too, kinda like a snake after it ate a rabbit.

THANK YOU TEGSOX !!!!!! finally someone else that agrees with the overblown chance of water in a cold air. :clap:
