A post that we all know can come up too often, What is a cold air intake and what are the advantages to short ram intakes. Ill start the initial post and if anyone thinks i have missed out something or am wrong please add it and i shall update my initial post. With a bit of luck we can avoid having four million threads on this here.

WHAT IS A SHORT RAM INTAKE?

a short ram intake sits in the engine bay, the pipe runs to a position behind the battery. heres a pic of an AEM V2
(note the position of the pod)
ADVANTAGES:
*Top end gains due to the free flowing setup
*Responce is greater than the cold air intake setups, due to the shorter flow for air to get into engine.
DISADVANTAGES:
*On hot days "heat soak" becomes a factor, hot air is less dense than cold air and on a hot day there is alot of hot air in the engine bay. This can be overcome by building a heat shield kind of box around the pod but probly wont be as free flowing nemore.
* This set up is illegal if using an oil based pod, In some states it is illegal to have an exposed pod in the engine bay. If you use a dry paper type pod it will be fully street legal.
SHORT RAM INTAKE BRANDS
*AEM V2
*Weapon R
*K&N Typhoon



WHAT IS A COLD AIR INTAKE?

A cold air intake runs the pipe through the engine bay and sits the pod in the wheel well, heres a pic of RacingHonda's setup, I believe its simota pipe with the Apexi Power Intake pod(shmicko!!!)


(note how the pod sits outside the engine bay)
ADVANTAGES:
*Its cold air diet means for a constant supply for cold air, no heat soak!!!better for power on hot days
*looks blingin!
DISADVANTAGES:
*long pipe is bad for response
*in really wet countries hydrolock is a risk, this requires the full pod to be submerged (knee high puddle) with atleast partial throttle applied (over 50% I'd guess). It doesn't take einstein to guess that water in the engine=VERY BAD=VERY EXPENSIVE, (well, too much water anyway, water injection can be a good thing if done properly, but that's another issue altogether) Hydro lock can be avoided by purchasing an AEM bypass valve.see pic below

I've heard its useless as it totally disrupts the airflow so u may as well stay stock intake. It's the big black thing about three quarters up Wickedlude01's intake pipe



COLD AIR INTAKE BRANDS FOR PRELUDE
*Iceman
*Simota
*AEM cold air intake (not v2)
*K&N Typhoon

Honda Prelude Type S Air Intake (OEM):

What is the Type S Intake? The Type S intake was developed specifically for the high-output Japanese Prelude Type S and SiR S-Spec. The H22A in these engines produce 163kW or 220PS through an upgraded valvetrain, intake, throttle body and exhaust.

The intake is specially designed to match the air intake wave frequency in the low-mid RPM range whilst having more volume to improve engine efficiency (power) in the high RPM range.

These changes can be seen below comparing the standard intake (upper) to the Type S intake (lower)





ADVANTAGES:
* Noticeable increase in low-mid range torque from 2000-4000 RPM (pull can be felt from ~2500RPM as opposed to ~3100RPM with standard intake.) - this is due to the chambered and tuned-length design.
* Can add K&N High Flow Panel Filter if you want improved throttle response and top-end power.
* Helps top end slightly if you plan on doing other mods such as exhaust.
* Improves driveability whilst being totally legal.
* No risk of hydro-lock to your engine or heated intake air from metal piping, which are attributes of other intakes.
* Won't attract attention if inspected by Police/RTA/EPA.
* Developed by Honda, hence has lots of R&D behind it.

DISADVANTAGES:
* Bracket must be made up to mount a solenoid that normally attaches to stock intake otherwise cable-tie if you're lazy.
* Can be difficult (and expensive) to find.
* May mark slightly on the top edge due to bumping into bonnet sound-deadening (if fitted).
* Throttle cable will not sit 100% flush in gap, as layout is slightly different to Type S.

INSTALLATION:

I have a V2 on my car .. I havnt really checked into the other ones , i had a V2 on my civic also so i bought it for the lude, Love the V2 though .

I don't know much about intakes but one of my friends has a 99 accord v6 with an intake on it and it makes a really deep sound when the rpm's go above around 3500. I was wondering if I purchase an aem cold air intake I will get a deep sound aswell.

sticking with the short ram is probably best youll avoid the hydrolock since the bypass valve is close to useless and your filter will get rusted out in a cold air intake that goes all the way down happend to my boy but ive seen them short ram with a half a shield kind of thing i wonder if that could help in the heat factor?

i like the cold air although the only experience i had was with the civic.. any way great post Brash!!

i used my aem cai for 4 years straight (2 on my accord, 2 on the lude, now its my turbo intake ) daily-driven year round without a single problem (i.e. hydrolocking) and theres not a spec of rust on it. without a bypass valve.

just dont drive like a dumbas$ and you'll be fine w/ a cai w/o bypass valve.

What kind of horsepower/torque gains can you get from a CAI and SRI?
After reading this, it seems like CAI is only better on hot days and the rest of the time, SRI has better performance. I always thought that CAI would improve performance better than SRI.

rep to joo!

Great post!! Think im gonna get a new V2.

The v2 looks freakin sexy I saw one on ebay new for $245 plus shipping do you think that is a good price?

^^that's about what they retail for

Brash,

K&N Makes a Prelude intake setup called the "Typhoon"
it can be applied as a shortram, or a CAI intake.
the tube is broken down to 2 pieces,
Long for the short ram, and a smaller elbow for the CAI
it also came with a sort of mesh bag that surrounds the filter to protect
it from the water or Hydro Lock i believe it was called.

I run the shortram version of this, and if you need picture reference checkout my members ride page,
[link posted in my sig.]

If you guys would like to see the mesh type thing they gave me just let me know here or PM me.

I got the ICEMAN but in California that intake is illegal.I got a ticket for it just thee other day. Im looking into getting a AEM.But dont know which one.

howd you get a ticket or it?
some guy pulled you over and took a look at your bay?
lol, wonder why the iceman is illegal

y would the iceman be illegal. it was probaly a racist cop

what?.....

in CA, aftermarket upgrades must be CARB legal and have the CARB LEGAL tag stamped onto the part.

i got pulled over by a officer.asked me to pop my hood.and got cited for a iceman intake.that intake doesnt have a CARB STICKER on it.so by that its "illegal"...idk.

__________________

why not just go on ebay and buy a carb sticker...lol. cheaper than a new intake and no cop is going to know the difference. especially after some time when it fades. oh and by the way if you live in a rainy area like I do in Jersey stay away from the CAI. I hydrolocked my engine 2 years ago. sucked bad but now I got my type s so its ok. and I like my type s intake too better than the AEM.

does anyone know anything about the greddy air intake for the prelude. It looks sexy but does how does it perform

You know you drive a Honda when your favorite letters are B, H, and K.

Just got the V2 installed and I think it was worth it.. Its not like a big hp gain but I love the deep sound around 3k rpm full throttle and when it hits VTEC its really loud too

Yea dude. I love it. I still remember the feeling of my first test drive after the V2 install. Looooved it. and still do.
Also, that little "psh" when you blip the throttle. Amaazing.

It performs just like every other intake on the market - the gains from stock will be huge in your head, but about 0.5-1HP at the wheels.

v2 ftw. im not a pro with intakes, however i did do my research. i have it on my 4th gen. once i installed it i noticed a smoother ride, quicker acceleration, and an awesome sound around 3600 rpm. very worth the money. the weight you save by adding it is also crazy. it's not a ton, i know, but it's a lot to anyone who races. the lude easily gets to about 120 now on public roads (not that i do that).

great post and thanks for all the numbers!

I put a Vibrant CAI on my 97 base. I get the same deep, rich tone around 3500rpm, the "phhsss" when you open the throttle and it seems quicker. I haven't dyno'ed it but I would say it gained a small amount of pickup. It was definitely worth the $70 I paid at Bap Geon. Alot cheaper than the "sexy" looking AEM or V2 or K&N short intakes and they probably have simliar gains if any.

i love my V2 intake, sweet ass suction/ whistling sound... damn things are expensive though!!
