Hey guys

i know you guys have probably been asked this a billion times before, but i searched and couldnt find something as specific as i wanted it to be...anyways...

Im looking at getting a cold air intake for my car and i cant decide on which one to get. I have an 04 civic ex coupe. What are the pros and cons of each one? I like the idea of the K&N being convertible to sri and also having a valve for preventing water from getting in. Since i live in ottawa and we have **** weather all the time im really scared of getting water or slush into my engine. Which one will "hypothetically" give me more power ( i know these really dont give you much power). Also, i heard Injen is pretty good, just wondering what you guys think....

v2 is not cold air. K&N is better quality from what i've seen. but cold air can suck up water and mess up the engine.

I say V2. You don't have to wory about rain or water EVER. AEM now has the dryflow filter which is cool. I have the dryflow filter, and I wouldn't go with any other filter. You don't ever have to oil it ,you only have to clean it every 25,000 miles. It's the easist intake to take care of that you will find. If you want an intake that will give you power that you don't ever have to worry about get the V2.

yeah, but doesnt the typhoon have a water shield with it as well? which one will give me more power?

Mine never came with a shield.

does the V2 have any effect on mpg?

I have just the regular sri and my mpg seems a little better. So, I'm sure the V2 will give you a little bit better mpg. The CAI is probably going to give you a little more power ,but not much more, and there is going to be more to deal with. Even with a water shield you still have to worry about deep puddle, the shield won't be able to block water when it's under water. There has been many times when we have had hard rain, and I've been so glad I got the SRI. I could still drive I didn't have to stay home and worry about the rain.

i have the version 2 now. The sound is just incredible w/o an exhaust. It has this like deep grunt its just mean lol. Had a cold air at first but being lowered I coudn't afford getting hydrolock. I noticed some torque loss down low after the change but you make it back up on top end lol. Who launches at 2000 rpm anyway racing? The torque loss is not a big deal in daily driving IMO.

U r all stupid. Everything that has been in this thread has been covered already.

Myth #1 Aftermarket intake = better mpg.
NO IT DOESN'T. The aftermarket intakes are less restrictive than the stock air box. Less restricitons = more air. More air available to the engine = more fuel burned. More fuel burned = less mpg!

There are dyno sheets all over this site for numerous intakes on both manual and automatic cars. I know that Gearbox has done a review on like 4-5 intakes by himself; not to mention all of the other members.

I'm pretty sure that non of the intakes make more than 2-3 peak hp and most the noticable gains are b/c the people who installed them have had other mods on their vehicle ( header, exhaust, ect.) which all help.

Basically you might as well go with an ebay intake for $30-40 just for the sound.

FYI some intakes even lose power (only about 1hp but still and they lose TQ)

Ronaldo: You're right in staying 'who launches at 2k rpm" but think about this. Who launches most of the time when they are driving anyway? No one. Even if you consider yourself a "street racer" or you just like to race the kids at school, I bet you're only doing that less than 5% of the total time that you drive. Which means that 95% of the time you have less TQ for every day driving which our cars are already very short on...

I had an intake for about 6 mo then I took it off and I'm happy that I dont have it anymore. Yea the sound was cool for awhile but then when u downshift to 3rd when you're on the highway to pass someone and your engine sounds loud as hell but you're still accelerating slow as ****, it looks really stupid. Espically when that 60 year old driving the Buick that you were trying to pass punches it and passes you instead. LOL

like all aftermaket filters, it's supposed to increase MPG. But the ppl tend to step on the gas harder after having an aftermarket intake so......
K&N Typhoon Injen CAI pick either 1. AEM V2 if youre worried about hydrolock. Nothing against gearbox, but his car was auto, and pretty much everything he has done for power was wasted. There are some gains.... but as for just about all 4 cylinder engines designed for economy, dont expect much. And umm..... buy ebay intake at your own risk.

the weapon r intake was the only one that i heard that has actual noticable gains..as told by gearbox. Its funny how everyone is worried about there engine sucking up water with the cold air intakes, you are an idiot if you drive through a two foot puddle and than maybe it would actually suck up water but you can also get a bypass valve which is supposed to prevent hydrolock. I have had my CAI on for over 2 years now and i get blizzards, terrential rain and hurricanes and i havent had one problem yet, if hydrolock is your reason for not getting a cai...well than you are stupid and its also convertable to a short ram air intake...obviously.

as no one has mentioned this yet, the bypass valve restricts any hp gains you may have gotten to prevent water from going through.
Thanks

also the bypass valve wont work unless the entire filter is under water. if its not, the filter will just suck in water.

 
Rep Power: 475

if you drive through a huge puddle that makes the whole filter get covered in water...you deserve to have your engine hydrolock

i had injen cai and now a v2 and i like the v2 best. as for k&n, i thought fipk II was the better one to get, not the typhoon? honestly, you should just start saving for a turbo if you really want power from that engine

i tried a regular aem and the v2, they are both really loud and i couldnt tell any difference performance.i heard the K&N and its also really loud. the noise wasnt worth it so i took it off.

I got the V2. I like it. Looks good under the hood. Sounds cool too. Not too loud at all imo. No water worries with it either. I can feel a little bit more power with it. MPG about the same but def did not go down.

First of all to everyone saying Don't get one at all, get over it. In one way or another ie..( sound, power, mpg's, looks) it's gonna be better than the stock air box. Just the big cool looking pipe under the hood is enough to get one. And as I have learned if you really want something for you car your gonna get it one way or another, even if it does nothing else but look good. That's one of the main points for all of this. To take a stock car that is every where you look, and make it you own. To make you car stand out from the masses. So like I said above V2 easy to take care of, little less power gain. CAI some water worries even if you don't have hugh puddles your still gonna worry some, just because you don't want a hydro locked engine, but a little more power, and harder to get to the filter to clean it. Thank you all. and before someone says it's not harder to get to the filter. You have to get down under the car to get it on a CAI. Where on a SRI it's right there under the hood.

why does everyone say you have to go under the car to get the cai filter...YOU DONT!!

 
Rep Power: 338

^^^ I can see how that is for AEM CAI, Injen CAI, from what see, may require you to get under the car to clean filter.
I have been here a while and have not seen a whole lot of hydrolock threads compared to the amount of CAI owners on here, but it does happen.... even sometimes in not so heavy rain conditions. Aside from bypass valve, I think K&N also makes this kind of wrap around the filter and that works well.

 
Rep Power: 475

i just have to move or take the battery out to get my filter

 
Rep Power: 338

^^ which CAI do you have?
found the wraps:
http://www.knfilters.com/wraps.htm
from description, it's to prevent dirt........ but when I washed 1, water hardly passed through.

 
Rep Power: 0

all K&N cold air have the wrap. its to prevent water from going in. you're supposed to take it off if you goto the track cause it robs airflow.

secret weapon R all the way.... now only if i can cough up $170.

 
Rep Power: 338

ahhh, I see.... it's a replica of AEM CAI...... easier to clean than Injen CAI

 
Rep Power: 0

Most of the CAI I've seen mount the filter at the bottom of the front bumper. So, I would think you would have to reach under there to get the filter. Having to move the battery is a bit more trouble than just lifting the hood and taking the filter off. Also any filter wraps or shields are just going to restrict air flow and take some of the advantages away.

the secret weapon looks good. has anyone seen this testing? kinda puts the other ones to shame. and 170 isnt that much compared to other ones.

gearbox has the weapon r and he tested many intakes and he said this was the only one with noticable gains...but he isnt on this site anymore
