Default (DIY) Custom Inkate

(In case you were wondering DIY = Do-It-Yourself)

So I like the stock "ram air" my Legacy came with, but hated the piping because of all the air leaks, so here is my response to it....

:THINGS NEEDED:

- 2 1/2 pipe custom bent to go from the stock airbox to the stock inlet (Went to Mieneke and got it for $30. Make sure the pipe butts up to the back of the inlet and the front of the airbox. You DO NOT want it overlapping, just flush.)

- 3 inch universal radiator hose (Get the kind without the steel-threading, the fabris-threading is the best. It sells by the foot, so just buy 1 foot of it.)

- 4 hose clamps(Make sure the clamps will fit over top of the hose)

- Whatever tool needed to tighten the hose clamps because it all depends on what kind of clamps you buy (Screwdriver, socket, etc.)

- :OPTIONAL: Scuff pad, primer, and paint if you want to paint the pipe. (Rattle can paint is fine. The high heat engine paint is your best bet.)


:TOTAL SPENT: $45


:INSTALLATION:

:OPTIONAL: Scuff the whole pipe with your scuff pad, then take a piece of strong string through the inside of the pipe and hang it to the ceiling. Spray 2 layers of primer, then 2 layers of paint and let it dry.

Cut 2, 2 inch long pieces of the radiator hose off. Place the hose OVER top of the stock inlet piece and place the clamp on top of it leaving just a TINY little bit of the hose showing (less then 1/4 on an inch) Tighten the clamp down. Place the pipe inside the other end of the hose. Slide another clamp down the pipe, overtop of the hose, then tighten it down.

Take the other piece of hose you cut off and 1st put it over top of the airbox plastic pipe, and clamp it down, then place the steel pipe in the hose and clamp that side down also.

Done!

:PICS:

I haven't painted it yet because I wanted to make sure everything worked out. I am going to paint it later tonight and afterwards I will post more pics.

Good idea! I was contemplating doing something similar some time ago, but never got around to it!

Impressions? Butt-dyno results?

Oh yeah! Knew I forgot to add something!

Well coming from that stock thingy, there is a big difference. You will not believe how much air is lost in that plastice piece of crap. Noticeable sound change, reving up is alot faster especially between the 5000 and 6000 RPM mark. Before I know for at least my car it was really chugging in that area, but now it is just perfect.

It was well worth the $45 I spent on it.

If you wanted to, I bet you could pull your front inlet off, take the air-filter out of your box and get the pipe bent down into that hole in the fender and put a cone filter on the end to have somewhat of a CAI (Cold Air Intake) system...

Meh, after some DIY projects, I'm satisfied with the general idea of the OEM intake system. Getting rid of some of the bends and air leaks as you have done, and I'm sure its better than any aftermarket system (at a fraction of the cost).

Nice lookin setup! I have been thinking about doing something like that since I would like to keep the stock airbox, since I have been told as long as you do you won't lose any low end power, which sucks already (stupid automatic).

Sweet setup! Now you have that cool WOT growl/intake noise. IMO the sound is worth the 45 bucks alone

Black car's engine bay looks SO much better than my white bay. Oh man does it need a cleaning.

Great mod, btw! I might have considered doing this had I not spent $40 on my "no modification necessary" Ebay intake. (*cough* BS *cough*).

Wow! Even better painted!

I'm starting to think I made a mistake using blue under my hood. I now have three colors to deal with.

Time to paint my intake, I guess! And clean...oh so much cleaning.

Now, I may be confused, but I didn't think that ram air scoop got a whole lot of air flow through the grill/hood. I wonder which is the better option, this, otpulling from the fender?

Personally, my thoughts are:

A. Air being forced into intake through grill at XXX speed. (OEM style intake)
B. Air being pulled from a comparatively "dead air" compartment blocked on all sides by plastic, metal, etc. (fender wall)

I think A is better than B, but what the hell do I know.

I was just under the impression that the scoop was mostly blocked by the hood, and didn't see that much airflow.

I would almost bet that if you used some sort of air flow meter, the upper grill area near the intake would get stronger readings than in the fender wall...

Yes and no. From the factory they have a dam attached to the hood that blocks a lot of the flow but when you remove that it opens it up.

I have been thinking about this intake deal for a while as fibuz and others have I am sure. The fender is dead air as stated, the short ram just ends up sitting above the headers and sucking hot air and the stock system is OK I guess but none of the options seem worth the work or money. I can not seem to come to a much better than stock solution so for now I just leave it.

Devil,
Did you get the bend angles prior to going to the shop or just have them bend it a bit and the test fit until it was right?

I went to the shop and at first the guy tried bending it like the stock bends which are 2-90 degree angles, but the pipe kept getting crushed. Finally i told him to try it the way it looks now with the 2-45 degree angles on either end. Worked the 1st time

i'm still gonna amke a set-up that draws from the hood scoop as soon as i can afford that damn carbon fiber hood... but for now, i just took off everything and am drawing air from inside the engine. it gave a tiny bit of performance boost, but for the most part just makes hard driving sound better...

You guys running upgraded exhausts? Even with a snorkusectomy pulling air from the fender, my car sounds much more like a very large sewing machine than "growly".

maybe I should do a write up for a 95 legacy wagon, I need a cai in that bad boy, its dying for more air!

i've made one for my corolla, (hardly a wrx burner, but its got more balls than my legacy wagon slushbox!) A better place for piping is JC whitney dot k(c)om. They have mandrel bent stuff for cheap.

The corolla cai DIY is found at my website, ill try to post it in my sig...same concepts apply to any car.

*EDIT*-->
The website is posted next to my name I guess in the scroll down box!
Check out the review on SSR Competition wheels, delicious.
