Okay. Before you hit me for -1 please read the following.

When I had my accident a year ago I slightly bent my frame where my air box is. When it was straightened out, it wasn't back to exactly factory perfect. So now my air box doesn't fit perfect. It rattles. So I've been thinking. A solution would be to remove it and put a cold air intake in. I'm not doing this for performance. That would be a waste. I want to do this strictly so I can remove the air box and end the rattling. Can I use a short ram cold air intake? What manufactures are good? Can I just bolt it on and be done with it, I don't need a tune do I?

Just looking for pros and cons to this solution. And again. This ISN'T for performance. I'm just OCD about little rattles here and there. And there's no way that air box will fit properly ever again.

Make a bracket and bolt it to something sturdy. Problem solved.

The air box is bolted in sturdy. The part it rattles against I think is the plastic tubing inside the fender. The plastic tubing inside the fender normally connects into the airbox. But now it doesn't. It's kind of just flush with the hole to the air box and rattles against it.

On an N/A you dont need it tuned or anything so go for it.

Is the filter in the airbox, or is it in a separate box closer to the engine? If it's the latter, you could just remove the airbox.

I've got nothing again the idea of an intake....but cheaper way would be to just throw some foam between the plastic and the fender

or the 'snorkus delete' as someone already mentioned

DO NOT do the snorkus delete if you go mudding with this car... i found out the hard way.... hahaha.

ummmmm, we might be thinking of different mods? I'm just talking about replacing the giant in fender airbox with a smaller piece like the GPmoto Elbow....I can't picture that making a huge difference to sucking anything up

rshaw123 · « **Reply #8 on:** December 06, 2011, 10:46:15 AM »

well it depends on how you do it. I removed the inner fender box on my legacy completely and I know BlackParis just cut the snorkel part off. Both of those ways would cause a problem if mudding but the delete will bring the opening back to stock location and there wont be any issue.

deadlydave · « **Reply #9 on:** December 06, 2011, 10:48:19 AM »

My advice: if your fender liner is still in tact, pull the snorkus out of the fender.

TylerBeau · « **Reply #10 on:** December 07, 2011, 11:13:55 PM »

I'm confused now. My filter is in the air box. Then there is tubing that is in the fender.

I did try the foam solution. Still rattles against the tubing that is in the fender.

rshaw123 · « **Reply #11 on:** December 07, 2011, 11:16:25 PM »

you can by a fender delete pipe. I don't know where to find them but its a easy swap and then you wont have any more rattles.

TylerBeau · « **Reply #12 on:** December 07, 2011, 11:17:59 PM »

That might do it! I'll look into that.

rshaw123 · « **Reply #13 on:** December 07, 2011, 11:26:13 PM »

after my brother hit the deer in my legacy, I just removed the entire box inside the fender, but then you run the risk of getting water and debris inside your motor. The delete will just be a piece of plastic that will go from the airbox to the stock mounting point up near the front fender.

TylerBeau · « **Reply #14 on:** December 07, 2011, 11:32:11 PM »

So does it remove the box with the filter too? I want a filter still.

Kavik · « **Reply #15 on:** December 07, 2011, 11:48:14 PM »

this is getting confusing LOL

your engine bay looks like this, right?

your filter is in the |_\ shaped box where the maf attaches to
in the very front left corner, just above that yellow cap for the power steering fluid, is a small air duct to pull in air from the grill area.

that air duct goes into the fender, meets up with a piece that should look something like this:

that piece then feed back to the air box

the 'snorkus delete' mod just replaces that piece in the fender, either by hacking off the bottom of that piece and resealing the area you cut off, or using a GPmoto Intake Elbow that looks like this:

some of those pics may reference different years/models, but it should be the same basic principle

TylerBeau · « **Reply #16 on:** December 08, 2011, 12:42:52 AM »

I see now! Haha. Thanks Daryl. I'll look into that for sure. That or the cold air intake. The intake will still get proper airflow to the engine correct? I know that sounds dumb. But just curious.

rshaw123 · « **Reply #17 on:** December 08, 2011, 12:53:11 AM »

if you do it correctly. Some people just throw one on that stops right above the heads of the motor, like the one on my old car when I bought it.

edit:
Sorry my post wasn't very clear, I was working on math homework and studying for finals. It made since to me when I wrote it

TylerBeau · « **Reply #18 on:** December 08, 2011, 05:55:43 PM »

I was going to get one that stops where the air box is... Is that okay?

Dave · « **Reply #19 on:** December 08, 2011, 06:32:09 PM »

Dont remove the airbox, you will most likely get a CEL. you can replace everything except for that and be fine. just figure out whats rattling and take care of it in whichever way you see best.

Kavik · « **Reply #20 on:** December 08, 2011, 08:22:36 PM »

there is no guarantee that you'll get a cel removing the air box

I've had intake on 3 cars and have yet to see a single cel

I can't say what's the best intake for this car, I've never looked into intakes for an N/A Impreza, I'm just here to argue that blanket statement

my 2 cents still lie in the airbox delete and leave the rest alone though

^^^^ This is your best bet, the intakes that most people put on stop right above the motor (gets nothing but hot air). There are some that go into the fenders and actually work quite will.

like so. Its a Injen CAI with an AEM 3" Dry Flow Filter

Kavik · « **Reply #22 on:** December 09, 2011, 12:46:20 AM »

but then you run the same risk of sucking up water, same as if the fender air box is just removed

actually, the risk is even higher with how low the filters sit on those. I had a Perrin one in my blue car and I cringed every time I hit a puddle, especially with the hole in my fender liner

TylerBeau · « **Reply #23 on:** December 09, 2011, 06:47:56 AM »

That intake is what I would get. Which would work and fix the problem. But I think Daryl has a point about the water. I guess my best bet is to get in there and figure out exactly where the rattles are and see if I can fix that. Last resort being a new intake... Maybe if I just stuff my fender with a bunch of foam. Haha. Just kidding. Thanks for the input guys. It helped a lot.

Yea, the whole...water...thing scares me. I'd just get a decent looking/decent priced used CAI where the filter is located in your air boxes old location. You could make an SPT-like heat shield for it if you wanted.

You're not going to gain or lose a noticeable enough amount of power on that engine anyway. Go for good price, ease of installation.
