Talking Injen Cold Air Intake Update

I just purchased an Injen CAI kit for my wrx.

I have heard lots of complaints of it being scratched by the fender metal and also vibration between the intake and fender. So people have used pieces of silicone vac hose, etc to prevent this.

Just want to say that Injen now includes a nice soft vinyl strip that prevents this scratching and vibration. In case anyone was worried about that.

I will update when I get the install done.

i didn't have any problem installing the injen. you have to use the force when putting it in. go with your feelings luke. i pushed it up and back and twisted it right into place. it doesn't go straight in.

Ok,

I got the Injen intake all installed and its great so far.

-No major gripes about the install
-DO NOT remove the entire bumber, headlight, foglight and wheelwell as recommended by Injen. That will just be a waste of time. You can do it all with just the removal of the plastic wheelwell insert.

-Instructions were very short and simple, yet clear. Follow them and you'll be fine.

-Haven't done much driving yet, but went for a quick spin and it doesn't seem to have added a whole lot of power. There is a noticeable difference in sound... especially loud air rushing in at high rpm.

-Anyone have real dyno numbers for this upgrade?

Almost everyone I know that had one has sold their Injen intake.

Anyone have any good PROOF it works good? Like before and after mile runs. With the Injen the ONLY change?

I'd like to know.

Unless your engine is modded well, I wouldn't expect ANY power gains. I have AEM CAI(supposedly the best one out there) and I had absolutely no gains. People did dyno runs and lost a couple horses. I think one guy said something like -.15 sec in the 1/4 mi. When yoiu get an exhaust and/or new turbo you'll be glad you got the intake first! It will greatly imporve your car's ability to ingest air into the turbo. Without it, you won't see the full fruit of your Modding labor.

Stop quoting a magazine. it was more then likely a paid advertisement. These are the same guys that said the wrx had a 2.2L engine.

all I have to say, is wait until you get either a cat back, or a turbo back exhaust, it really sounds mean all together.
especaily in traffic, when you are getting on it a little, people
always look to see if it's a jet engine, or some monster engine lurking under the hood

I got mine when they first came out last year. At first, I was a little diappointed with the lack of power boost when driving around town, but I did notice the difference when I tried to merge with traffic on the highway. The engine seemed more eager to rev, and I had a little better top end acceleration also. Another side benefit is when the turbo wakes up and you are cruising beside someone. Sounds just like a jet engine spinning up! Also gets the attention of pedestrians also!

Purchased and installed Injen CAI. I have the following to report:

* As said above; DO NOT REMOVE THE BUMPER/HEADLIGHTS/FOGLIGHTS
* I installed through the wheel well.
* Install time: 2 hours. Could do it in 1 hour if I had to do it again.
* Sounds Great - lots of air swooshing and BOV sounds. I like it.
* I have noticed that I have less turbo lag
* My feeling is that a CAI alone is not worth it, but when combined with the turbo-back exhaust I'm about to add it will essential... plus you get a great sound (I haven't listened to the stereo for days)

Thats all.

I've had mine for 1 year and 2 months now and have no complaints. It seemed to spool a little quicker, but agreeing w/ everyone else...you need to get exhausty of some sort before you should notice more improvements. I also agree: don't remove the bumper.

***Rubber Suround Notice***
I used a semi trailer brakelight rubber surround, cut it in half and trimmed about 1/2" off and it seals everything and allows no vibration. Works awesome. It's like a 4"round brake/blinker light surround.

With the addition of the injen, I picked up about a tenth in the quarter. My tests were done with a vericom computer. The computer may be a little off from the track but is great for before and after tests. The last time I went to the track with it I was right on with the time but it showed 2mph too high.

so far everyones reviews of this item are on a WRX. Anyone have a 2.5RS that has used this intake and have any reviews? I need to do something about my intake. I have a few mods done to the car but right now im only hitting 83 at the top end of the quarter. I still have the stock airbox/tubing to a cone filter in my 98RS. I am looking into either getting an injen or a weapon R i guess since the choices for us 98 guys are limited. Any suggestions?

( i found this while doing a search so Im still searching for those of you that would suggest to do a search )

I also have had no problems with the intake, however i am worried about water. I know not much gets in there, but how much water actually needs to get into the intake to cause damage?

The amount of water needed to cause vapor lock is probably near the amount of volume of the heads combustion chamber. Damage occurs when the piston cannot move up/outward toward head during the compression stroke and you get a bent rod or worse.
I do not know the actual amount though.

The Injen CAI has a uniform (about 2 inch) diameter which is very compatable with the OEM air flow meter. The AEM is 3 inch stepping down to 2 inches at the AFM. The APS (Cobb) is much larger at the AFM, and the AFM doesn't see the entire true air flow, and requires a chip specifically programmed for the APS intake. All I know is that the Injen pulled about 2 1/2 inches of mercury less vacuum at idle than the stock air box with a K&N filter. I interpreted that as improved air flow, at least at idle. Seems to work O.K.

Low mounted CAI source can suck in water very easy if you try wading through deep (a foot or two) standing water. The water quickly stalls the engine, but it really doesn't take much water to severly damage the engine. The primary risk of engine damage is usually due to relatively small amounts of water reaching hot exhaust valves and warping them.

I had a CAI in a dropped 2000 accord w/ little protection from exposure from rain. I live in FL, so if u know anything about our summers, you know it rains here everyday. thing is i never had any problems with my cai. Just avoid floods of water. If you are worried..most CAI come with a by pass value or you can buy one.

OK I have both the AEM cold air and a Perrin short ram
1. AEM does not change diameters at AFM. I measured ID of both the AEM and stock, they are nearly identical.
2. AEM netted more power but It is very hard to tune since there is a bend right before the AFM.
3. Perrin sounds meaner than the AEM but it choaks with fast shifts
4. It is much easier to tune the Perrin with my S-AFC
5. Perrin caused a CEL and AEM didn't

hydrolocking with a wrx is a hard thing to do people, i mean you must be doing some serious wrc stuff, just driving in the rain is not enough to hydrolock the engine...come on??? dont you think the people at AEM or Injen might have thought about the fact that rain is a natural weather occurence???? unless you are hitting a 2-3 foot puddle, (i doubt it) then u can just chill..btw aem does not make a bypass valve for their cai for wrx applications
