Cold Air Intake......

wallgood358 · Post by **wallgood358** » Tue Dec 05, 2006 10:54 pm

I found a cold air intake that claims it was made for my 92 Legacy Sport. 2 different versions actually. So i thought i would spread the word. http://www.jcwhitney.com/autoparts/Vehi ... 37/c-10101

It's a generic style pod intake, and from the pics, it doesn't look like it'll work with the turbo motors.

I think CAI's are kinda worthless, I'd suggest getting a K&N pannel filter that fits in the stock location.

Then go and "de-snork" your intake tract. If you don't know, "de-snorking" is basically taking out all the intake silencer crap up to the air box passed through the fender wall. That way it sucks air from the fender and straight into the intake box, just like a CAI would do.

Cai's are not worthless if built properly and that can only usually be properly done by modification and customizing it. The effects are usually not felt by NA vehicle or of intake is the only thing done. Exhaust, injectors and other things are needed to fully reap the benifits of a CAI

I should have re-worded that... I just think, if you want more power there are a bunch of other parts to spend $$$ on before getting a CAI.

I will probably build a CAI for myself, but thats when I have a td05, boost controll, intercooler, and various other mods done.

So basically, I'd only see a benefit from spending that much money if I was going to be adding a lot more flow w/ a bigger turbo and whatnot...

I understand what you are saying for the most part. But how your car breathes is one of the biggest things for power. Plain and simple

I still say the stock airbox with its velocity stack is very well designed. You can improve flow by adding additional air inlets, or by cutting the bottom of the box off.

What do you mean by 'won't work with Turbo motor'?

Also, I can understand that some people would rather cut holes and take certain parts out to make OE better without spending much cash but, $$$ aside wouldn't a performance designed intake be better than any OE mod?

I meant it won't fit.....without modifications, and without added an extra bracket & tubing to put the MAF sensor in-line.

There is MUCH more engineering that goes into OEM stuff then all the aftermarket crap out there.

For example, take a look at this pic
http://www.main.experiencetherave.com:8 ... ystack.jpg

It's a picture of the inside of your airbox. The gold metal piece is obviously used to mount the MAF to, however it also serves a function to help smooth the air out as it enters the MAF, which helps the MAF read more accurately. In addition, flow will be greater across this type of transition vs. a square edge.

You won't find many, if any aftermarket performance stuff that has something like this.

I support legacy777's ideas.

I think the only thing you might be able to gain from going to a conical filter is more surface area to pull air in from.

I second that...Josh is dead on...

I am running 20psi on a VF8 and I still use a stock airbox with a K & N dropin and a 3" bellmouth inlet in the side of the box in the stock location.

On a MAF based system, you'll get more performance out of a well-metered but lower flow system than a turbulent high flow system.

If our cars were MAP based, Id say by all means, throw in a cone and cram in as much air as possible, thats what Im doing (new ECU is MAP based)

All the air in the world is useless if it's throwing your A/F ratios out of whack.

I'd have to support all the nay sayers on the idea of a CAI...

You'r money is better spent elsewhere...

I used a '98 Legacy GT intake box on my SS. Also chopped up a steel cocktail shaker to serve as the "coffee cup mod". Seems to be a much smoother air path (eliminating the 90* bends)

Dynamic Entry · Post by **Dynamic Entry** » Mon Dec 25, 2006 11:44 am

I am pretty much convinced.

As soon as the busy holidays are over I am going to de-snorkify!

How did you re route all of the vaccum hoses that connect in there?

That is super sketchy...I dont mean to sound like an ass but that doesn't look very reliable or well thought out at all.

mattyg41383 · Post by **mattyg41383** » Fri Jan 05, 2007 4:01 pm

I dont see how thats any more sketchy than using a coffee cup... and it eliminates the bends of the stock air path, creating a smoother air flow. That was a picture taken before completion, so obviously there are the necessary clamps and hookups on it now. Holes were put into the bottom and back of the steel portion to run the Vacuum lines, while keeping them somewhat hidden.

I noticed a big difference after doing that. Its been that way for about 5 months now (hot weather and cold) and have not had a problem or any signs of pinging.

I really like what you did with the airbox. That is what I want to do to mine when I get caught up a little bit. What did you notice after going this route. More mpg, smoother, or more hp?
I think I am going to try and get a 45 degree rubber hose on the end of the maf sensor and then I will have to come up with something to go in between the 2 pieces of hose as there won't be enough room for the coffee cup thing.

Hello Matt. You out there?

mattyg41383 · Post by **mattyg41383** » Sun Jan 28, 2007 12:11 am

Sorry, been among the missing.... working. When i first got the car, it was in rough shape, so I only babied it from the guy;s house to my shop. Did the intake mod before it was tuned back in to shape, so I dont have a side by side comparison. But combined with the snorkus removal and that intake refreshing, it drives extremely well... and Im still on Stock boost until i get time to do my FMIC install. No hesitation, so problems since August when i got it, driven pretty hard. Intake and blow off/recirc sounds are much louder =

I recommend it.

jefferson · Post by **jefferson** » Sun Jan 28, 2007 12:18 am

I am giving some thought to getting the car on a dyno while it is completely stock so I can get a baseline and then do the mods and see what happens. I have made some friends at the local Subaru dealer and one of them had the airbox sitting around so he gave that to me. Guess I need to stockpile parts and then bite on the dyno pull.

I was just cleaning up the new airbox and noticed that the velocity stack at the maf opening wasn't there. Did yours have one and if not did the one out of the old airbox fit? I would think it would fit and would defineatly be something you would want to do. All the more for better airflow.

Good idea, I dont recall if it did or not. I'll certainly check it out next time I'm under there.
