Intake question. . .

[misnomer]

Would you see a difference between replacing the entire intake system a la Injen versus just slapping on a good cone filter? What else, aside from a shiny pipe and red wires, do you get from the Injen system?

Thanks,

if you just use a regular intake there shouldn't be much of a difference, but there will be a difference if it's a cold air intake/ram air intake vs just a regular intake. I'm not sure that makes sense... simply put, a cone filter isn't that dif from a regular intake but a cold air/ram air intake is better than both a regular intake and a cone filter... Hope that helps.

i can't give you numbers, but i could tell a big difference after installing the jwt pop-charger, also a difference putting a cae leading up to it. also sounds much better. the car definatly revs faster.

If you buy just a cone filter, you'll get nothing in terms of performance.

Thats not true. K&N's are designed to allow more air to pass through the filter with less work than the stock filter. Some stores have a demo they can show you with a ping pong ball that is pretty amazing. Personally I dont like the whole cold air intake idea because it puts the intake so low to the ground you can end up sucking in water/snow and screwing your engine over a 1-3 hp?! If the injen intake has a larger diameter then it will allow more air flow over the stock setup, but if they are the same then I say just get the cone filter.

The injen intake is significantly larger.  In fact, it barely clears the hood

That intake doesn't require battery relocation does it? I'm planning on moving the battery anyway, but I'll have to wait a while longer on my intake if i've got to relocate the battery first.

I have a different question: I installed an INJEN intake in my '91 240 a few days ago and as soon as I revved the engine, I heard a mild "swoosh" sound. Now, my boyfriend has a '96 240 with an AEM intake and his does not "do the swoosh". Is there a difference in power between the two intakes? Does anyone have a similar experience???

where is the sound coming from, does it sound like air coming out or air "swoshing" inward (if that makes sense). either there is a leak or that is just the sound that your intake makes, an intake usually does change the sound of the engine alittle.

It's definitely coming from the intake. I think it might be because I left the bottom half of my stock filter box on the car so that I don't get all the hot air into the filter. I figured it's probably the echo of the air coming into the filter from its bottom. It sounds cool, no complaints!

is it a sucking sound? I get that on my 98, it's the vaccum sucking in air cause the engine is not getting enough, so it's probably the intake box in the fender blocking air, I need that taken off too.

As far as the CAI goes, out here I get 'bout 9 inches of rain a year, rest of the time it's usually pretty warm. Think it's worth the extra money? Anybody got one they don't want anymore? :-)

[vancouvers14]

it rains here lots too.  Havent had trouble with it in the rain, but i got some water on the filter when i was washing the car and it overheated.  fine after that.  In the winter, just turn the filter to face forward.

in the s14, you dont have to move the battery.  shouldnt have to in the s13 either.

as for leaving in part of the stock filter box, why?  chances are, the stock pipe is smaller and would be restricting airflow

[misnomer]

9&quot; of rain falling in an area about 10ft by 10ft is about enough to feed one sagebrush for a year <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'> Needless to say, getting water in the intake isn't a big worry. If the CAI is easy enough to remove, I can pull it out for the wintertime, where we get most of our moisture

I used to check for moisture in my stock air box and never found any. Now, what I was thinking when I left the bottom half of the box in was that it might get me at least some colder air rather than having all my air come in from the engine bay. There's that headlight cover with a scoop for a ram-air intake for S13s. The guy with the red S13 featured on this site has one. They cost about $90 and are more or less an answer?!

Have you ever looked down your stock intake pipe? &nbsp;It's full of irregularities and constrictions. &nbsp;The Injen intake pipe is larger and much smoother, allowing for better flow and more air. &nbsp;As far as blocking engine heat from a non-CAI setup, why not make a heat shield. &nbsp;Maybe a pretty effective budget heat shield could be fitted out of cardboard, reflective/foil tape, heavy duty double-sided tape, foam tubing, and a little trial and error. &nbsp;I'm gonna attempt this when I get my Injen in about a month. &nbsp;If I figure something out and it works (I'm even gonna take before and after temps), I'll post instructions/results.;)

I don't remember exactly where, but I saw these little blue buckets which fit exactly over the cone filter and which sucked in the cold air from the bottom of the filter, I guess. I've heard of people who took single bottle drink coolers and wrapped them around the intake pipe and it made only a bit of a difference. (This was done at the strip.) They said it's not worth the trouble-not for street &nbsp;racing.

From anywhere, for $49, you can get an Injen brand &quot;moisture / heat shield.&quot;
It covers 1/2 the filter element and is a nice polished chrome piece.
I have the Intake and CAE on my car, and I get the swoosh. &nbsp;I am guessin that it is the engine getting a need for a lot of air and the intake giving it. &nbsp;It only happens when I rev the engine tho.
Ohh.. the water thing. &nbsp;K&amp;N filters are water-resistant. &nbsp;I live in south florida, and a couple weeks ago, it rained like ####. &nbsp;I drove through a 4&quot; deep puddle to get out of my house. &nbsp;I went 20 miles in a torrential downpour, and then pulled my car in my gf's garage. &nbsp;Took off the filter, and checked for water. &nbsp;99.9% dry. &nbsp;It just felt cold... might have been *slightly* damp, but no water drops or anything of the sort.
btw... the extension really is kinda hard to get out, you need to take the tire off... and the wheel well.

I'm running just a K&amp;N cone filter on my s13. &nbsp;However, the hole bellow the filter (where the resonator box was), I installed a piece of 3&quot; aluminum flex tubing. &nbsp;I extended it from the hole below the filter to the end of the splash skirt which runs between my bumper and skirt. &nbsp;For those americans in the crowd who have that black grill where us canadians have a set of running light in our bumper can install that tube behind the vent.
It will cost you less then 15 bucks in tubing and zap straps.

[vancouvers14]

on the s14, you don't have to remove the tire and wheel well. &nbsp;All you do is remove the splash guard from the bottom, and reach through there. &nbsp;That's how I installed mine, and its the easiest way to remove it. &nbsp;You only need a Philips screwdriver. &nbsp;I'm experimenting with just turning my filter forward in the rain. &nbsp;Will let everyone know how it works, but so far so good.

use a 10mm socket... it is better because those things can be tight... dealers use 10mm to put them on...
