Engine The sound that CAI makes...

Yes it is noticeable from the outside... on my Civic, i've had a few people actually ask me if I had an exhaust on the car, and all I have is a short ram air... its a deep grumble at low rpms on mine and get higher pitched as the rev's build, I love the sound...

The sound that CAI makes...

I'm thinking about getting a cold air intake, but I hear it makes a loud sound. Does it really? My car's engine(03) is stock right now, so what will the difference be? Also, are CAI's bad for heavy winters?

My CIA makes a swooshing sound.. You get used to it after a while, a nice sterio system helps , naw it's not that bad, but it is noticable. nothin like a modified exhaust sound though.

it only makes sound when you pass 3000 RPM and it gets louder after that

Is it annoying? Anyone have a sound clip or video?

What would this be for?

What would installing that without a CAI do?

Does the CAI interfere with the warranty on the car?

Its not really annoying (usually).

Thats a filter that goes on the end of a CAI. Installing only that filter and not the intake system would cause the car to A: Not Start or B Start, stumble and cut off.

The CAI can interfere with a warranty depending on how aggressive your dealership is about warranty work. Some places don't care, and some will cancel your powertrain warranty.

im a dumbass, why would the car cut off? all i can think of is that you need to mount the sensors in some sort of fashion to monitor air flow and temp- but thats it no?

Thanks for all your help so far guys. Lol, does it at least sound cool?

it sounds AWESOME! since its a longer tube and the filter is usually hidden (or away from engine bay) itll sound quieter than short ram...BUT, the sound pitch will change b/c of the longer tube=deeper sound- physics 101- and this is also a speculation- but i believe those cars with stick seem to sound alot different than automatics as far as intakes go- w/ stick, there seems to be a spooling, real rich, growl, with an auto- it seems like a steady drone..

it sounds very deap... very nice sound...

my friend's CAI sounds like a vaccum cleaner his Acura CL

He has a 2003 which uses a Mass Air Flow sensor in the intake system. If that sensor doesn't pick up any air movement, the ECU will think the engine isn't getting any air and wont start it.

If you dont have a MAF sensor and just put a filter directly on your throttle body, you're not going to have any pressure before the throttle and your car will run like crap if not constantly stall. It probably would cut off if you had a MAF sensor too.

Temperature is important for measuring air density.

the CAI on my 98 sounds really good, especially if i have the AC on...lol, i turn on my car and the first thing you hear is SSSSSSSSSSSSSSSSSSSS, and then the exhaust helps also. I remember when i put on a Short intake, i was all freaked by it, WHATS IT DOIN!? then hes like, spaz, its ok. then i got a real CAI, and the tone got deeper

I used to have my true cold air intake which was in the front of my ck1 body kit. I swear I felt boost once comming off a hill, but yea that sssssssssssss-sound is really neat sounding, and when you rev up it sounds like gulping air

Actually, that sound is not only because of a longer tube, bu also because you ditch the resonators. These just swirl the air around in a large compartment (behind the bumper plate), so that it is not just a straight through vacum, but the air is slowed before it hits the TB.... thus deadining the sound.

This is another reason why CAI's are so good, quicker airflow = more efficient injection = more efficient burning = more power.

BTW... they sound Awesome!

Is the sound noticeable from the outside of the car? What brand do you guys recommend? It is bad for hard winters/using the AC?

I have Injen intake for my 04' Corolla S, its soooo tight, but the only part that worries me, is that every time i turn it on in the mourning. It has this loud hissing sound and the engine is super cold and takes like 2 mins to hit mid-range on the gages, and the only way the gage increases is if i drive it, i can't just let it chill inn the driveway and let it warm up. My friend who knows a shit load about cars and installed it for me says that its ususal... but i dont know. It runs good thou, weather the gage is cold or warm. lemme know if this should or should NOT be happening, thanks. Oh yeah, if the hssin sound when turning it on is usual, then INJEN is the way to go, its definately worth the 250, not only does it give u 8-10HP but, it also gives u like 1-2 MPG too!

the hissing sound is normal

the hissing sound is definitely normal and quiets down after the car warms up. The sound is aggressive and the difference is notieceable on a NA corolla and more such on a FI'd engine. I have the Injen, but had to cut it in two places to get it to fit the SC. If you plan on getting a TRD SC in the future for the 03 and up, go with TRD CAI. More expensive, but the only one that currently fits well. It is like they planned it.


if you go to corollatoys tthere are vids of various setups.

I'm going to film my car on the dyno tomorrow and hope to get vids up on a site somewhere.

yea, i have a SRI that i bought on ebay, and it sounds freggin awesome. Sometimes I wish I still had my stock exhaust so that all i could hear was an intake sound.

IMO here are the CAI Pros/Cons

Cons
Filter is hard to get to for cleaning
Hydrolock can be an issue
Most are not C.A.R.B. certified (Cal. Air Resource Board)
The quality CAIs are $180 plus
Decreases mpg a bit due to the increased hp (but is this really a con?)

Pros
Cold Air = More Dense = More Power
Engine seems to respond better
Aggressive Sound
Filter Cleaning Intervals are 30K plus
You can run AC and everything else like normal
The Quality Ones are getting C.A.R.B. certified
Make your engine bay look sweeter
Easy to install (30 mins or less)

Hope this helps

more hp = more mpg? I'll call B.S. on that. the mpg increase may be a result of driving habits. I do however believe the gains on the CAI in general on the 03s and up.

I love my AEM CAI...it does "hiss" when it's cold but when your engine warms up it's great. I love the sound i get from it and and the gains are nice as well. You definitely sound more aggressive.

Rolla Dink is right on the TRD CAI....if you do plan on going with the TRD CAI...it's the only one that will fit correctly unless you decide to get a short ram or cut it in a few spots like rolla dink

actually his didn't look to bad from what i saw at the Dyno today...oo send me my vid when you get a chance rolla dink!!

In thw inter time I usually warm up the car for a few mins before I leave, if I get a CAI should I still do that?

Using AC do anything bad to the CAI? It would be helpful if I could get a list of pros/cons of getting a CAI.

Ummm, drive you car as you normally would, just enjoy the sound, and the few ponies you gained, and inspect the filter periodically to make sure it is clean and replace it at regular intervals... otherwise, drive and use your car as your normally would...

i think itll be the year 2225 b/f an intake like injen gives 8-10hp...

Nope, sorry samurai, its called the year 2004, and i have the horepower increase, so dont hate cause u got AME V1 or some shit, i even dynoed the car after just to see if injen was bullshitting in their papers they sent with the intake, but they were right 8-10HP, sorry to prove u wrong, but im just so damn smart, lol

Yeah that does help, thanks Rolla Dink. What is hydrolock? I'm going to wait till spring to get one. I'll have to find out if it will affect my warranty though. Hopefully not.

lilbeastie18... id love to see the before and after dyno sheet on your particular car...

Hydrolock is when water gets into your engine, and as you know, water cannot be compressed whereas air can be compressed. So what happen, water gets into a cylinder, and then the piston can no longer move up because it can't compress the water, and basically ur engine dies, if ur lucky, there will be no damage (not likely), in other cases, your engine needs a rebuild, because parts broke inside from the stress... but if you are smart and dont drive in very deep puddles and odnt submerge the filter, you should be fine...
