No it wont work. The WRX/STi air intake is routed differently due to the turbocharger system. You need something that would either connect directly to your throttle body (check out Injen for this) or something that connects to your filter box (Ganzflow). I would reccomend the injen myself, but people use the Ganzflows and report good results with them.
I have never heard of or seen that intake. I would be wary of it because it says it fits both the WRX/STi and the RS. Thats a big red flag because the intakes for the turbo motors go under the intake manifold into the turbo, whereas the NA setup does not have enough room under the manifold for an intake tube to pass through. Long story short, anything designed for a turbo application will NOT fit an NA setup and anything designed for an NA application will not fit a stock turbo setup. I would never buy any product that says it would fit both a Subaru NA motor and its turbo counterpart.
As for the question about short ram vs CAI, it all depends on what you want. Short rams do not suffer as much from low end power loss like the longer CAI's do. But their advantage at the top of the RPM range disappears unlike the CAI's. Why? Its all related to the lengths of the respective intakes and what the length does to the intake air velocity across the RPM band. CAI's are longer than short rams, hence airflow efficiency at low RPM is not as good as the short ram. Its important to note that these losses are not too much however. CAI presents the risk hydrolocking or ingestion of water into the engine, but it would take a significant amount of water to do that I think. I have never heard of it happening.
i also have an 05 RS. Does the 05 RS come stock with a cold air intake? because the intake goes into the fender well. Also, which is better: a intake that goes to the fender OR a short ram intake??
cai is way better than short ram. i noticed more of a diff going from sri to cai than i did going from stock to sri. that intake in that link looks like its just the second half of the cai, because it says that it will also fit a wrx/sti.
You can modify your stock air box to run CAI and use a less restrictive filter then stock. Use a straight piece of 3" ABS from the box into the inner-fender (or 90 degrees pointed to the back of the car).
Use some silicone (black) to seal the box and pipe. Use any non-oiled filter (MAF cars), HKS, paper STI, etc.
This is of course after a 'snorkus' delete. It will run as well as a $250 CAI or short ram intake. Be sure to reset the ECU. I just ran Injen for the 'bling'...
Disconnect the battery, depress the brake pedal, and turn the ignition as if you were trying to start the car and hold it there for five seconds. You should see your electric odometer go blank.
After the reset...
Does the ECU set it self back up to the bast fuel mileage and rpm settings, or do you have to know how to set it up so you don't have junky gas mileage?
Sorry, I forgot to answer this in my other post. The ECU will relearn with the new mods. It will find the best trim settings by itself. It takes some time though, when I run 30% E85 it takes about 70 miles or so to really learn the new mods/fuel composition.
just buy an ebay intake and put a better filter on it! You will save a ton of money... a pipe is a pipe. Then buy a AEM sticker and put it on! Kazam! You have the same thing for less then half the price!
and another question, I live in Reno, NV where it snows. So going with CAI, couldn't the wet snow clog up my air filter say if I drove up to go snowboarding?
Well I've only had mine on for a year, and I haven't had any issues in the snow last winter or the heavy rain we've gotten lately. I dont snowboard tho, so i dunno about how tahoe would affect it. As long as you keep your fenderwell out of water and snow, it should be fine. Injen also sells a hydroshield to cover the filter, and I put that on so that may make a difference.
A snorkus delete intake is a good idea. I have a PDM intake which is basically a 3" aluminum pipe that runs to the stock airbox. I'm in the process of retrofitting a 3" elbow into the airbox to get even more flow while still retaining the box. Well here's a link to my newly finished intake making it a true 3":http://www.rs25.com/forums/showthread.php?t=84807
:hijack: Where can I get 3" aluminium piping? I'm making one of these myself. I bought PVC piping, but something tells me its not going to work out well.
DONT BUY IT!!! IT IS A HOAX! YOU LOSE MILAGE AND POWER!!!
Unless you want to lose milage and power but have a nifty little intake insert, then go ahead and but it! Actually buy 10 of them to get a super vortex in your intake! :lol:
I do want to put a cold air intake in my 03 RS. I just bought the car a couple weeks ago and want to put some work into it. I am on a tight budget tho. WAY TO MANY SCHOOL LOANS! anyone know about a good not too expensive cai?
On top of my 2005 RS stock intake there is a little black chip with wires running into it?? What the hell is that and what do i do with it if i replace it with a pipe????
ok, now i'm looking at buying a cheap pipe from ebay or something, and putting a better filter on it, with a hydro-shield or go SRI...
Now this filter:
says it fits a 97-01 subaru 2.5rs
My Subaru is an 05, but everytime I open my hood, I still see this intake fitting in there although it doesn't have a fit for my date. Would this pip fit an 05 RS? I think so, but I would like some second inputs...
you just want the filter? It should work, as long as the pipe you get is 3" in diameter. if you want that pipe too, then it won't work, because there's no place for the maf sensor.
anyone know anything about spyder cai? there real cheap like $75 cheap. I have a 03 2.5RS and want to put a cai into it. if I bought this would it be worth it?
the only things needed to be done are plugging up the vacuum line opening, and cutting off approx. 3/4 to 1" of tubing at the end where it goes into the fender. Obviously you wont need the filter that it comes with or the vacuum hose but for 30 bucks it was worth it for me!
if i do get a cai should i go into the stock airbox or take out the airbox all together? advantages? disadvantages?
