Air Silencer

[CHROMEDCRUISER]

I removed the black lower "snorkel" silencer today. I noticed a very deep sort of WOOing sound at higher RPMs. It sounds great, and the car seems to be accelerating about the same. My only question, am I cutting off air to the intake by removing the snorkel completely? I don't want to hurt the engine. I own a 03' TE 5 spd. If there was a considerable amount less air coming in, would the air flow sensor come on followed by the check engine light? Any help or guidance would be gladly appreciated.

I removed my white silencer and my snorkel on my GT. I taped up the holes in the snorkel and put it back in and drove a while. I then took the snorkel assembly out completely and am currently running this way now.
With the snorkel out, there is a huge area for air to come in. This is good. The only downside is it is all hot air from under the hood since the snorkel is no longer sucking in cooler air from the fender hole. This is bad.
I am planning on making a part that will go over the hole and route it to the fender. I'm not sure how the n/a box differs from the turbo box though. I know with the snorkel removed there is a big oval area for air to come in.
It sounds a little louder and it seems to drive a little better without the snorkel in it. I have had it out for about two weeks with no ill effects. No engine lights and it does seem to run a bit better.
You have a choice - restricted cooler air or a huge volume of warmer air. I chose the latter and am happy so far even though I plan to modify more for cooler air intake.

The small white piece, yes, but why remove the snorkel? It sucks air from the wheelwell, cooler than under the hood. Why remove it? Don't think it'll hurt anything, except maybe mileage a tiny bit.

By removing the snorkel you just about triple the size of the air inlet. You can get as much air in as the car can handle, no doubt.
With the snorkel in, the air is more restricted. Maybe that is all the engine can breathe in and by opening it up you are not gaining anything. I don't know. I just think the more air the better.
As for hot air under the hood, many manufacturers make intake systems that have no heat sheild or cold air induction whatsoever. Even Adam's V.A.K. system that he sells has a cone filter with no heat sheild and no one seems to complain.
With the path that the air takes on the turbo, I doubt a "true" cold air system would make much of a difference. On a n/a PT, maybe it does. The n/a does have a shorter path to the intake.

DREAM2, cut the piece off that goes into the box flush with the inside of the box. Then pop the snorkle back in. The result is you keep the snorkle and draw in colder air from the fender and there is no restriction in the box for more air. If you want to remove the third silencer you need to replace the pipe that goes from the turbo inlet to the air box. The factory pipe narrows down to 1 1/2' inside that pipe.

I plan on getting the Brand X pipe and a K&N drop in at 15,000 miles (which should be about next week) and also switch over to Mobil 1.
I want to fabricate a piece that will replace the snorkel and utilize the larger opening in the airbox when the entire stock snorkel unit is removed. I just really want that larger volume of air that this will allow. Will it make any difference in performance? I don't know, but I'll feel better knowing I have the largest possible opening for the air to come into the intake. I just have to get to the stores and check some things out that may work. If I find something that can work, I'll post what I did so others can try it too if they like.

Think you will like it--I DO! [8D] [?]

To those who started to take the silencers out (like me) and didn't have specific instructions, I thought I would add more detail. ('cause I couldn't figure out how to get the air box out for example).

I have a 2004 2.4L

1. take off hose to turbo (in my case) that comes off the top of the air box using a screwdriver to loose the clamp. Pull it back an inch or so out of the way.

2. release two latches holding air box down (one on each side).

3. Lift off the cover towards windshield. There are 4 or 5 plastic slots holding it onto the back. Take out air filter (remembering dirty side down)

4. Don't do like I did and try to take out the two silencers while it is still in the air box (doh!). At this point the air box is held down by plastic studs that go into rubber gromets. Just rock it back and forth a little bit and pull straight out. (or sorta straight out as the snorkel has to clear everything.) Go ahead and give it a good tug! After it is loose and you can get your fingers on it, pull off the small blow back hose attached to the left hand side of the air box. Finish by pulling the airbox the rest of the way out of the engine compartment.

5. Now you've got two chores. First, in the top of the lid is one white, round piece of plastic leading to the turbo hose. With a screwdriver you can pull back a white tab inside the opening and then it will slide UPWARD out of the lid. Take the whole thing out.

6. On the air box, use a flat screwdriver to push on the two releases top and bottom on the right side of the air box. You can then wiggle the "snorkel" shaped piece until it slides out to the right. Removing the two top clamps by loosening their respective latches, you will then see the bottom silencer that is filled with holes.

7. I used duct tape and covered them all up top and bottom. re-install the two clamps and push the "snorkel" back into position.
It should click into place.

8. Re-install everything in reverse order making sure the air-filter is not upside down, the blow back hose is connected, and the air box has a good seal.

Hope this helps! [8)]

I keep reading about these silencers, but will your instructions work on a regular PT not a Turbo?

[CHROMEDCRUISER]

Yes, mine is a 03' Touring Edition, no turbo, and there are two silencers that are easily removed.
