missing air cleaner parts

[A.J. Tarnas]

I bought this wagon a month ago, and the VIN plate says it has an "EJ221CWAWL" engine. But the engine configuration doesn't match EJ22 images I'm finding on the internet. I don't know the terminology for the cold air intake components, and it seems that several of mine are missing.

 

This is my car:

 

It seems to match this engine better:

Can anyone identify the items I've drawn lines and numbers to (1, 2, 3), or ID what should be connected there (4, 5, 6)?

 

#2 looks like the air filter housing ("air box"?) and it has a filter inside (NAPA GOLD 2728-062808AC1). Is #3 the mass air flow sensor?

If the car runs as is, without the end that's open, you wont have a MAF, as you car runs on a MAP (manifold absolute pressure) system.

 

If you car will not start, you need a MAF before you worry about anything else..

 

Let's say you don't need that and the car runs, here is where we are.

 

1. Air inlet/intake tubing

2. Airbox/filter housing

3. IAT or air temp sensor

4. SEE BELOW

5. A silencer elbow to eliminate noise on the OEM setup

6. Hard to say from your picture.

 

 

***4. That is where a big black box should be connected too, better known around here as the "snorkus". It actually goes into the fender well and picks up atmospheric air that isn't already heak soaked by the engine bay. THIS IS NOT A NECESSITY.

 

I feel as if #6 isn't anything that is that important and if you think it is, try to get a better close up

Just read what car you had, and that whole entire setup is exactly like my car.

As an EJ221 (which should be a P2 EJ22), it's setup will be just like the EJ251's found in the later Legacys.

Nice, thanks for the response. Yes, the car runs fine as is. It has a dozen things wrong with it but all relatively minor except impending head gasket job.

 

Here's a better view of the entire engine compartment:

 

 

And here's underneath the air intake tubing:

 

#4, #5, #6, #7 are not currently connected to anything. If I wanted to order replacements for these missing items online, do they have names? What's the official name of the "snorkus"?

[DOHCEJ22E1]

Helmholtz Resonator is the official name for the snorkus.

This looks like it actually might be the right assembly at a decent price:

This seems like it could be the correct diagram:

Yes all those pieces are for quieting down the stock intake.

[A.J. Tarnas]

Huh, welp, just bought that ebay listing. But even without these components, this car seems incredibly quiet to me (which I like).

[Sludgeroo]

With that big airbox it would. I would recommend a k&n OE replacement drop in. Will take place of your existing filter.

 

I may have any of the parts you don't end up getting if need be.
