I know this is probably posted a bunch of times but I didn't see any. I am looking to get a cold air intake for my 92 Si4WS. I was looking at the Iceman but they don't make them anymore so now I am looking at the AEM anyone got any suggestions? Any good places to buy them? I was looking at preludeparts but anyone know any place better?

 

i'm gonna add a question to this...

does the 5th gen AEM fit on a 4th gen lude?

 

I don't think that the 5th gen intake will fit on a 4th gen because when you order them you have to pay extra if it is a 4th gen. Also I believe I have read that the 4th and 5th gen have a completely different intake system... I am not 100% on this though just makeing and educated guess.

 

Iceman is best for the 4th gen.

 

Hmm I don't know where you read that! They are the same intake system...but basically the 5th gen engine sits further back in the bay, err the nose sticks out longer, so the bends in the pipe are a little different and a little different length. You can make them fit but why bother...

4th gen : 2.75"
5th gen: 3"

 

Iceman is better than AEM on the 4th gen??

 

I had good gains (seat of the pants) when I had my AEM installed. THats the only one I have ever experianced, other that a hot air intake on a 5th Gen so I cant really reccomend anything but the AEM

Jonesy

 

I would probably say Iceman, but they are damn ugly. I think their advantage is the heat resistent material that they use. The AEM looks nice and performs great. I have yet to see a DYNO comparison between the 2.

 

because that's a big difference in airflow

 

You think so? It's still limited by the TB inlet

 

I wanted to get the Iceman but the company that made the Iceman went out of business so I can no longer get the Iceman. I had ordered the Iceman but I was told that they do not make them anymore and that no one can get them. So is the AEM the best second choice? Does anyone know where I can get an Iceman still??

 

IT'S A FREAKING PIPE. Get some pvc and slap a filter on the end of it.

 

the diameter doesnt do squat..as long as the intake is the same size as the throttle body, wont hurt anything, im running a 2.5 AEM on my lude and it definately doesnt hurt my power..peace

 

not exactly. i suppose you know that velocity of the air moving into the TB matters as well. for that matter, 2.75" is actually better. as long as it can fit on the TB either one is fine.

 

Iceman has a tapered design which noticably increases intake air velocity, a good thing. Iceman also tapers down to 2.75'' (99% sure) just like AEM, which means it will have better intake velocity and will be able to flow more air than the AEM.

Honestly, when I had my AEM CAI I didn't notice much in gains at all. If I could have done it all over I would have went with iceman. Or I highly recommend a short ram intake with a good custom heat shield or heat shield box.

That is the dumbest advice I have ever heard! PVC pipe can not handle the heat so in turn it will release harmfull vapors that will damage your engine. That was the big thing with the Iceman it was made of a very similar material but would not give off these vapors. Does anyone know if they still make the Iceman?? If so where can you buy one??

 

I agree very much with Mike95lude. I have had the AEM short ram for almost a year now and just recently I built a sort of ghetto rigged aluminum air box just for ***** and giggles. As soon as I put it on the car I noticed gains in throttle response in both 3rd and 4th gear. My newest project was to create a sort of ram air effect from the lower portion of the front bumper by removing the intake resonator and fitting tapered piping up to the short ram's cone filter. That helped even more.

What I'm trying to say is this: Don't go shelling out close to $200 for a CAI, just purchase a short ram and play around with different things. You'll be suprised at what you can accomplish power wise.

 

I have a feeling ICEMAN's aren't made anymore but it looks as though you can still buy them here. http://www.inlinefour.com/salicinsys.html

 

are you retarded? or just plain ignorant?

 

Two words for you bud..... Venturi Effect. Learn it well.

 

Well, if you don't want a ghetto pvc pipe then get some inexpensive short intake. I honestly see no justification in spending $175+ on an AEM CAI.

 

^this guy is on the money. the tapered design generates more flow velocity, than a constant diameter design. diameter has EVERYTHING to do with it. a smaller diameter will increase flow velocity, as well as a longer tube. where as a bigger tube will allow more air flow, but youre losing velocity at the same time. so whats the solution? a tapered design, starting big, and ending small. i believe the iceman intakes start at 3.5" and taper down to 2.75" (OD)

Nitro at Endyn stated in their archives that the "ideal diameter for an intake is when the intake has 25% more cross-sectional area than the TB's bore cross-sectional area. Your TB diameter (overbored or not) dictates your intake diameter."
-Nitro from Endyn (possibly paraphrased by Tuan)

"Time for some basic trigonometry here and remembering that the area of a circle is pi x radius squared and the diameter = 2 x radius. For a 64mm TB the best value for an intake diameter is 2.8 in. This makes the Iceman tapered design (from 3.5 in. at the filter opening down to 2.75 in. at the TB) , at least theoretically from a fluid dynamics point of view, better than the constant 3 in. diameter."
-Tuan

theres my 3 cents with a little backup support from reliable sources.

peace

 

I've got the old AEM intake on my 4th gen w/ an actual funnel connected to the pipe, then the filter. Much bigger filter. Paid maybe $150 used for it w/ an extra filter.

If I had to do it again, I'd make a custom one. I think there was a write-up somewhere where someone used a U bend from summit. You could also buy a cheap short ram and extend it w/ some piping. Then paint/wrap/whatever. Save your money. You might get 1-2 extra hp w/ the "name" brand intake. Not worth it IMO. With the money you save, you could buy a custom exhaust.

 

anyone thought of running the intake to a vented hood. seems like that would be an idea?

 

As long as it never rained.
