Im assuming N/A engine refers to the engines that get no love on this we love subaru forum (lol, irony)

okay heres my deal. i have a 97 impreza outback, ej22 engine. I know I can get some more juice out of it, and I don't think I should have to spend a fortune to do it.

I already knew that the ebay part would provide considerable gain over the stock part, it's a given. just eliminating the airbox and using a filter with more surface area, more surface area=more air intake at any given time the engine is running. that being said, i have a few things to say about this.

1) i believe the filter matters more than the tubing, so using the ebay tube, (ugg properly adjusted to fit even though they promise no mods required) or even the stock tube, with a great filter will make most of the difference.

2) i dont know about you guys,(being sarcastic) but my outback sport, came with a scoop and 2 vents on the hood. one of those vents seems positioned just right to squeeze some cooler air into that open element air filter, or perhaps, allow some heat to escape, hmm...





3) it seems subaru made all kinds of room for mods in my 97 engine bay, and provided no performance parts or kits to upgrade with, whats worse than that, is they left me stuck with a one peice MAF tube that must be used in any CAI scheme



find one here: http://search.stores.ebay.com/subaru...sPageNameZWD1S



--- they sure were right about an engineer weeping...(remember that commercial), but can't we just use the maf from say, an 03? or any other sooby where the maf can be removed from the oe tube via those 2 screws and inserted into the aftermarket one? perhaps the plug is the same or can be rewired? it's still obd2 and the type of data it sends out is the same, so i don't see why this can't be done to make life easier.






also, to solve the rain coming through the vent and into the filter problem, i was thinking, just using a big magnet you can throw over the vent when it rains, like the ones people use to advertise their businesses on their cars, they make em pretty big and strong.

comments? questions? FAQ

Q is that your car

A no but I have the same exact model. and i was thinking about painting it that color, till i found this pic, now im thinking about paining the woodland or urban cammo pattern or maybe taking all the paint off like a delorean

imagine a stainless steel colored scooby... hmm, maybe i can even modify the doors...

and when that baby hits 88mph...


of course, i can always chrome plate the entire body, and get a licence plate that says "blingthsbich"


and people will stand there as i pass by saying ooohh shiny...

and that my friend; is exactly how i feel, welcome to my world.


basically, right now I'm still scouring the forum for ideas, and answers before I ask over asked questions, I'm looking at my options.

I am however trying to figure out what i can do, if anything at all (besides having a shiny new paperweight) with a Mitsubishi te05 turbo, someone might give me, it was pulled from a 94 saab 900. but that's not at all related to this thread, so i'll stop there.

i am thinking that a dry foam open element filter might do some good with the ebay intake tube under my proposed idea, perhaps if i wash it, frequently like i wash my home a/c filters?

hmm, there is no order in your thoughts; you listed numbers but they are almost all just scattered ideas..

i'll just comment overall;

the maf adapter idea, you can't be sure that your specific maf for your car will fit in every maf adapter ever made, maf's are different between the generations that had them, my maf wouldn't work with yours and so on.. so just simply switching the wires wouldn't make the ECU happy

also the maf section that is used in all cai applications for that specific maf is there for a reason, thats why 05+ CAI's use a specific thickness as air flows past, or the MAF is not as effective, thats why when i made my DIY SRI intake; i used the OEM maf section because well; it's the best. what's worse than skewing the flow of air than skewing the flow of air past the sensor that controls how the engine runs

best off just doing what the image says, even with the giant "LOL" Plastered on it, but with the filter element of your choice


unless the rain water directly falls onto your filter element i wouldn't worry about it, i backed up once into this spot which my car would roll down, it rained hard; i have a reverse cowl that let water in drip down the intake and soaked my filter.. but no damage done after that, just no flow and the car had trouble idling, thats all. all this talk of hydrolock garbage is pure speculation of the ultimate punishment of water in a engine...


the turbo, i won't start..

I get that. and my thoughts reflect my feelings about the information I find when researching this --erratic and fragmented and a bit of eccentricity, but unless you're rich, your not eccentric, you're just crazy.

I know not just any MAF will work, but I do want to know if anyone has ever tried using one of the easier to work with ones on a car, that has that retarded one? what were the results?

my maf died some time ago and my replacement part came out of a 91 legacy. an obd1 vehicle, the part is the same, the connector was wired differently, so i wonder, if we reset the ecu, and figure out to way to wire the maf, probably just plug and play, will my stock 97 imp-o/b ecu accept it?

or will it boot up and say hey who the hell are you and what did you do with my buddy then panic and stall the car

Qcanfixit: Um, take your intake apart. The MAF should be almost identical to the one you have pictured, there's just a hose clamp holding it onto the accordian like connection tube. It also bolts to the airbox using 4 screws.

I pulled my intake apart, and saved the 4 screws and the two "Nuts on a bar". I have a weird cone filter with a metal back plate, I simply drilled 4 holes and mounted my air filter directly to the MAF sensor.

If your current MAF is dead, your best bet would be getting a replacement off the same engine type you currently have. If you have a 2.2 liter motor, grab a MAF off another 2.2.

If the signals and voltages are the same, just with a different pinout, then if you can correct the pinout, your ECU wouldn't know the difference between the Original MAF (when it was working) and the replacement. However, MAF's are strange beasts, so goooooood luck with that.

My ebay intake robbed alot from me...from like 2.5-5k rpms I would make no power.... threw the stock one back one but I kept a cone filter on there and its so much better, sits right under the vent to.

So, at 6,000 rpm, and under 2500 rpm, it made tons of power?

Basically, all you did was an airbox delete. As long as it works for you...

Don't believe, know what makes the best difference. I know what I felt (even now) is not always what it actually is. Test the differences out, come to a conclusion and post up data.

Also, the tubing changes so much on how your car behaves vs an air filter. A huge vs small air filter will makes some difference but tubing length and width differences can move your powerband all over the place.

Earlier in this thread, I posted up the difference between the Minnam intake and the Ebay intake. Look at the powerbands. Totally different but with the same air filter. I do not have dyno data but I know when testing a JC Sports intake on another Scooby I own vs just using a panty hose over the maf sensor (Sheer Energy recommenced - ) made no difference in my 1/4 mile time.

It does both. At idle and low speed, it allows a tone of warm/hot air out (especially if you have your hood scoop opened up). At higher speeds, the faster, the faster the cooling IF you have a passenger side WRX bonnet hood scoop installed. Without one, you have no way of guiding air to your intake or engine bay.


I also wanted to add that I have had this scoop on since about 1998-1999. That's 7-8 years going through car washes and rain downpours. I have never had a problem with water. Don't worry about it.

Kinda lost at this thought. There are a lot of intakes, exhausts and pulleys to choose from. An aftermarket header is an option as well. Grounding kits may help some as well. As for the intake, you will have to be creative to make different setups. Over the years, there have been all kinds of homemade intakes made up with the maf equipped models. Good fun!

If have my scoop open. I notice it bogs slightly at lower speeds, then as airflow build up... Well, that went away mostly when I went from crappy spark plugs to VPower.

I got an ebay intake, and it took no modding to use. Though, mine was pre-shortened by the previous owner, I simply bought a brass fitting from the hardware store, stuck it into the MAP sensor hole, and ran the idle bypass vaccume hose right to the fitting.

Anyway, the bracket I was using to hold my air filter and MAF sensor stationary compared to the car's body broke, so I'm going to put the original airbox on, after a snorkusectomy (I'm going to have to buy a new splash guard for my passenger side, mine won't come off without breaking, tearing, and shredding like crazy. ).

Subaru Stars same exact intake

i have the same exact intake for my 1997 subaru impreza 2.2L base 4 door model. i was wondering what all did u do besides use the adapter and the rest of the things that i can see from the photo, is there anything that i would need to do besides the stuff i can see in the pics?

I have a MY 98 Impreza with a 2.2L. I was wondering if any of these cheap shortrams would replace the "torque box" and flex hose to the MAF? So essentially a want to remove my intake silencer in the fender, use my stock airbox and MAF location, just use a short ram to go from the MAF to the intake.

Here is my theroy, with the intake silencer removed the stock airbox would draw air from outside the engine compartment. With the air flow through the stock aribox the MAF would still be properly calibrated for its environment, and the short ram would provide better flow to the intake (less tubulent). So I can make a CAI without the pitfalls of screwing up the AF.

Am I even remotely on to something here or have just completely lost my mind?

Ok first off this thread has been beaten like a dead horse

Second and my own experience opinion

Get a CAI like the injen or the cobb i use the Injen and it works great easy install took under 2 hours and showed gains even over my short ram intake that i got off ebay and modified like everyone else. sure it is more expensive but search the for sale section sometimes these can be had for under $200. im not flaming since i am the guy who is giving up the NA world and turboing my 2.2L yes I AM BOOSTING MY EJ22 SOHC Single Port Exhaust

Unfortunately, you can't even think about it until after you've converted your engine management system to MAP. If you did that on your MAF car, you would be letting in a bunch of unmetered air, which would cause it to die off-idle and even if you were to get up to speed.. you'd blow your motor in short order from running extremely lean.

What is the install on this like? I have a 2005 Saab 9-2x Linear, which is basically an Impreza wagon. It has the 2.5 engine in it. My friend got the ebay intake for me, and I want to know how to install it.

I want to do something like....

Just an intake tube like this, with the proper 3 vacuum lines. Obvious that is for the WRX and such. Strap it on the stock box, and BAM.

Now I'm much happier about my e-bay intake. Knew it wouldn't fit so took it to a shop (i'm 18 and have no welding experience whatsoever) and 3 hours later (and $45) it was ready. Best $65 i've ever spent! didn't know it created that much power, but sure felt like it

Just make sure you swap out your filter to something good. It took me a while to notice it, but the air filter on the ebay intake was actually letting alot of dust into the intake. I ended up swapping my filter out for one by HKS, and replaced all the clamps and couplings with HTS products for added bling.

Although it may be slightly better than the ebay filter, the HKS mushroom filter has been known to let lots of particles through, much moreso than say a K&N or AEM and provides no more performance benefit for the lower filtration

One of the biggest things I've noticed with the price difference of a ebay vs. an AEM or like, is that the AEM, at least, are CARB approved, and you can't be hastled by the man. The ebay ones are only... cheap guy approved
Granted, you won't run into many issues having a CARB or non-CARB approved intake, but the extra cost is there for a reason (R&D, certifications, etc...)

I won't deny that an Ebay intake can give you gains, but if you're looking to stay 100% legal, that extra $50-100 can save that much in a possible fine later on, and also give you a much better out of the box fitment. leaving you with a 10 minute install, instead of hours of headscratching and cursing to get
an ebay intake to fit. The cheap intake, plus the price of a good filter (~$40-50), will bring your total cost that much closer to a good branded unit. Just save yourself the hassle and get a good intake, even if it's used

hmm, took me 10 minutes to fit a 2002 RS intake (now with a green cone filter) on my 05 RS, i.e. diff, intake manifold plenum, different sensor type, cut tube shorter because its smaller engine bay, routing the breather hoses etc.

it varies upon ability to work on cars between people..

but i won't deny the fact; if you want to spend the money for that fresh feeling in the back of your head knowing that you ' did it right '. More power to you.

Meh, don't get me wrong, i enjoy the feeling of buying something that i know will produce the best results for something

but face it, an intake is an intake, and as long as you have common sense, you really cannot do much of a hack job of it.

I don't recommend it but I have been running a 'crappy' filter on my Outback Sport forever. The car runs just as good as it ever has and the intake tract is clean. I don't know what to say.
