Default Intakes?

I did some searches and went to several sites. Now I have some questions. Most of the intakes seem to come down into the passnger side bumper area. Wouldn't this be bad since dirt and water are easily "sucked" in there? Also, I couldn't find much information about the AEM short ram air intake. Where exactly is it being mounted? And what are the differnt hp and torque gains and losses? Are the torque curves changed majorly with either? Thanks

Dont worry about the fender venting. Alot of us have been running like that for years and no problems. Just be a little more wary of really deep puddles (like 6" or more)

Dont buy a AEM. They lose massive low end torque. It is a quick hack attempt by a maker who doesnt understand the ej25.
Try
www.imprezars.com for the ganzflow (about $100, equal gains to the AEM)

Or the PDM intake ($50+shipping) basically the same design as the ganzflow.

Both of these lose minimal to no low end.

If you want upscale, try cobb tuning. www.cobbtuning.com They have an excellent intake with great gains, and minimal lose end loss.

All three intakes that Midwayman mentioned do not come down into the passenger side bumper area. Therefore, sucking in water is less of a concern with them.

I LOVE MY AEM INTAKE!!!!!!!!! NO POWER LOSSES FOR ME!
AND YOU CANT TELL HOW SOMETHING PERFORMS BY OTHER PEOPLE'S "BUTT DYNO".!!!!!THIS WASNT A QUICK HACK, THEY JUST HAD TO WAIT A FEW YEARS TILL SUBARU GOT THE MAP SENSOR ON THE 00/01, CAUSE OTHERWISE IF YOU HAD A 99 AND OLDER WITH A MAS/MAF SENSOR, YOU WOULD PROBABLY BLOW IT CAUSE IT IS VERY SENSITIVE..AEM DIDNT WANT TO TAKE THAT CHANCE OF SCREWING UP A MAF/MAS, CAUSE THEY ARE VERY COSTLY. IT HAD BEEN TESTED AND RESEARCHED FOR ABOUT A YEAR OR SO FOR A MAP, BUT THE RS HAS BEEN LOOKED AT FOR ABOUT 4 YEARS BY AEM. SO DONT SAY THEY ARE A BANDWAGONEER!
PEACE

Thanks for the info. Also, might wanna check your caps lock key StarDog. I think cobbs design seems like the best. The actaul filter is up in the engine compartment, is it not? Its just getting the air from the bumper, then actaully filtering it later, right?

The Cobb intake pulls air from the fenderwell, not from the bumper. The GanzFlow and PDM intakes also pull air from the fenderwell. Both of these intakes utilize the stock airbox whereas the Cobb utilizes a PRM conical filter.

Here is a pic of my PDM intake: [ CLICK ME ]

Ahhh stardogchampion... the die hard defender of AEM. They didnt care about Subaru until the WRX came out. Numerous people have reported the low end loss on the AEM. Not surprizingly this has been a problem with nearly every tube with a cone filter type intake.

How many times do we have to go over this? Tube style intakes like the AEM don't work, period. I guess people really don't know what low end torque is. Whoever has a AEM or Weapon R intake, try this: Drive really slow in second gear at around 2000 RPM or so, now without touching the clutch- floor it. You will notice that it crawls up to redline. Now, stick your stock airbox back on and try it again. You will definetly notice the difference, especially if you have a Ganzflow or PDM, I promise. Just test your gear before you start to post things like AEM is the best, because if you tested it, you will know that it's not. Good Luck!

Compass motorsports developed an intake that has a shiny new plenum box and heat shield. It's pricey though at almost $300!

Hi, since you own the RS, do your comments about loss of power (with the AEM) refer solely to the RS, or to any Impreza?

I have a WRX and just received my AEM CAI this afternoon. Since my car has little torque at 2000 rpm anyway, I'm assuming your test applies just to the RS. Just curious.

Cheers!

AHHH...bumper = me being really stupid. Also, what options do you have on pre-2000 models since the sensor is different? Is all you can do is put in a differnet panel filter? Also, what are the advantages/disadvantages of using the stock airbox (like the PDM) vs. a conical filter like the Cobb? And where can u buy the PDM intake?

hey, bouse1, I totally agree with you. The airbox acts like a resevoir for air. it always can supply air to the engine. whereas, a tube style intake usually has a slight lag and then it picks up.

as it's been said before, the RS needs that low end torque to get movin'.

so, AEM is defenately not the best intake. go for ganzflow, pdm and probably cobb. cobb has a good tube design, good filter design and it pulls air from the fender.

Hey bradus, with the WRX, i probably wouldn't worry about the intake. we talking about the gc8 RS and when your car is n/a, you have to be concerned about low end power loss and throttle response. it doesn't have the power to make up for little losses, unlike the WRX.

am i right?

any thoughts are welcome.............bye bye

Thumbs up almost forgot!

The all famous Compass motorsports intake. I can't wait for that to come out. That will be the best intake in my mind.

You can order the PDM intake directly from PDM Racing. As for the Compass Motorsports intake, it looks nice on paper and in the picture, but I will believe it when I see it.

Thanks Scubaracer, I believe you are right. Actually, I originally saw this post under NEW THREADS and didn't even focus on which forum it had been posted in. If I had, I probably wouldn't have posted what I did. Thanks all the same. David

On ANY turbo car, cold air period helps the turbo spool faster & cool the intake air to the turbocharger. On the wrx the aem intake is fine IMO, but on the 2.5RS its a POS imo .

Default AEM

hey ive been repeatedly bashed on this site for having a short ram air intake from AEM. honestly, i ahvent lost torque that i can feel. if anything i have a gain, YES throttle response is a little les, but that doesnt affect anything. its like when u are at idle, and u floor it. i just takes a second, makes a breathing noise and revs right up, the minute time does nothing. it has made my car a lot fast then it was thats all i know for sure. the intake possibly can have a loss of torque but nothing noticeable. I HAVE floored it at 2000 RPM with the intake on, and i race daily since ive bought the car, just with my friends and stuff nothing serious. but i know that it picks up a hell of a lot harder and really gets to redline fast. just because of all the trashing ive been getting i asked my guy to look at it. he drove it and agreed. yes a little lses throttle response, but nothing that isnt more then accounted for the 1/8 second later when it kicks and jets. its nothing to chop on. yes maybe PRM and ganzflow IS better. But AEM isn't crap.

hey by the ways guys. if anyone has actually seen the AEM, it looks practically the same as the cobb tuning PRM intake, jus tnot all the way to the fender. the bend is in the same spot coming off of the throttle body, and the filter is in the same spot, only with AEM it is a cone filiter, not the cylindar with the extension to the fender. i could add that if i really need to later. but im happy with how it is. if PRM is # 1 on the market right now, then how could AEM be total crap ya know? yea its not identical, but its quite similar compared to everything else out there with their differences. all i say is try it, if u dare. i love it, its 10times better then stock that i can tell you. ive had an exhaust for over a month now, and thats lovely, but with the intake it really brings it out. my baby screams like vtec and the kids that ride wit me and hear it compliment me daily. i wouldnt lie. im not here to make friends or enemies. just tlak about cars and stuff. maybe yours is better maybe mine is, all i know is that i like what i have and it works just fine

I dont think anyone will dispute that the AEM has gains. But its design isnt as good as some of the others. (nor as cheap!) Anyhow, if it works for you, great. Just letting people know about the better options out there. (and not to buy it blindly because its a big name)

Both of these lose minimal to no low end.

If you want upscale, try cobb tuning. www.cobbtuning.com They have an excellent intake with great gains, and minimal lose end loss.
Where do you get your information. PDM is a Canadian company that makes the filtering element for both the Ganzflow and Cobb Tuning. That is where the difference is made in both kits.

I have been in Texas. Cobb tuning uses PRM inline racing filters, not PDM. I should know, I put it in...

Yes, you are correct. A typo on my part. I did mean PRM out of Ontario.
