Aura Intake Resonator Bong Delete
 
With the lack of cold air intake options available to Aura owners, many people are wondering what they can do to free up the air flow to their engine and give it a big of a larger bark at the same time, like a CAI would do. Well the answer to this is simple, and not that much different than an actual CAI, anyway - remove the intake resonator bong.
"What is it?" you ask? Simply put, it's a piece put in place by OEM manufacturers to mute the engine noise - hence the name "resonator." There's really no other purpose for it. So by removing it, you remove a restriction of air flow into the engine, and also allow for more sound to be heard from your engine. Likewise, most CAI systems come with a new filter, usually a wire-mesh design (vs the paper type of most OEM filters) which also allows for more free-flowing air, but also filters the air just as well as they use an oil-based coating (which needs to be "recharged" every once in a while) to grab the dirt particles out of the air.

So, let's get on with removing this hassle now!

1) Jack up the front-right of the car - enough to remove the front right wheel.
Make sure to use the [U]correct[/U] spot for supporting your car, or you will bend the frame. You'll know the first one or two pumps after connecting if it's the right spot - if the car goes up, you're good, otherwise you'll see the jack sink right into the metal :eek:
[IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0004.jpg[/IMG]

2) Remove the wheel well shroud.
This is done by removing a myriad of plastic "screws" along w/ standard 7mm screws that hold this large piece of plastic in place. It's there to prevent water & debris from getting up into the metal of the frame and into the air filter as well. You'll want to just keep removing plastic & metal screws as you find them holding this piece in place. Here are a few of the ones you're looking for
[IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0005.jpg[/IMG] [IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0006.jpg[/IMG]

Along w/ the ones on the outer edge that you see here, there are also 3 plastic and (at least) one standard screw that hold a piece of this shroud up under the front bumper. As i said, as you start removing them and try to take the shroud out, you'll easily be able to pinpoint where there are more holding it in.
Keep in mind that this shroud is durable plastic, so pulling hard, coaxing w/ a hammer, etc won't hurt anything as long as you're smart about it. This shroud [U]does[/U] tuck into the exterior body molding above the wheel, so you'll have to get it out of that first for it to even come close to coming out. Likewise upon reinstallation this is the [U]first[/u] step to getting it back in.

[IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0008.jpg[/IMG]

3) After you get the shroud out, the resonator bong will be staring you right in the face along w/ a [U]single[/U] screw holding it in.
This should be evident as to just how menial this piece really is to the whole setup ;)
[IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0009.jpg[/IMG]

The 10mm screw here needs to be removed, and then you just need to use some brute force to release the plastic "rivet" that holds the front portion of the resonator in place. People who worked on Ions are more than familiar w/ these rivets, but the problem here is that there's not a damn bit of light that reaches the rivet up front to see how to get it out "properly." So some heavy coaxing by prying / levering w/ a pliers is what I used. It does nothing but hold the bong in place, so the empty, somewhat beat up, hole that's left over is of no consequence.

[IMG]http://i92.photobucket.com/albums/l22/bc3tech/How-Tos/Epsilon%20Res%20Delete/IMG_0011.jpg[/IMG]

[B]Note[/B] You can see after removing the bong that NOTHING is affected as far as the risk to the engine. The inlet to the air filter is actually [U]higher[/U] so there's an even [U]less[/U] chance of taking on water, and it's [U]still[/U] before the filter, so there's no more chance of getting debris into the engine.

4) Put the shroud back in, wheel back on, and lower the car.

5) Purchase a K&N (or similar) air filter to go into the stock air box, installation is straightforward. Remove the two metal clips at the top (closest to the windshield, visible in the first video in this post) side of the box above the filter and pull up on the top portion. It flexes easily to allow access to the filter.

6) Enjoy! Most people who have done this mod, or installed a CAI in a car, will tell you the first couple of things they notice are the sound and the better throttle response.

I forgot one last step (and restrictions in effect on this board don't let me edit posts after a certain time :upset:)

7) When finished and everything sounds good, you need to reset your fuel trims. You can do this via a device like the [url=http://www.dashhawk.com]DashHawk[/url] or you can simply leave the negative terminal of your battery unplugged for about 20-30min.
This takes the "learned" fuel trim (amount) readings that your car has developed over time and resets them so that in the next few miles it will re-learn how much fuel the engine needs in various conditions. This is needed because now the air will be getting a different amount / "quality" of air into it, so the fuel needs will change slightly. This isn't a [I]requirement[/I] for this modification, per se, but as a general rule whenever you change something that alters the air / fuel input to the engine, you should perform this operation.

You might have to do that if you had a fuel system error in the long term fuel trim or a fault in baro that kicked the fuel table way out of whack. The O2 sensor is responsible for adjusting the short term fuel trim and reacts instantaneously. This is how you can drive your car from the beach to the mountains without having to adjust anything. If the short term trim is continuously deflecting + or - 20 percent, the computer will select a different fuel table in the long term fuel trim.

Also, disconnecting the battery for 20 minutes does nothing. You need to deplete the stored energy to kill the keep alive memory. You do this by removing the negative cable and stepping on the brake pedal five times, or hold the disconnected negative cable to the positive cable for those five times.

Finally, while removing the "bong" creates more intake noise (which gives you the sensation of more performance), it does nothing for performance or at least no more than tribal graphics would give you. No air flows through the bong and if no air flows through it, it can't possibly be a source of flow restriction. It creates an inverse sound wave based upon the air flowing past it and resonates that wave back into the intake to cancel the sound.

[quote]Also, disconnecting the battery for 20 minutes does nothing...[/quote]according to my DH, disconnecting the battery cable for this amt of time resulted in LTFT's of 0 upon startup, prior to that they were valued.
[quote]Finally, while removing the "bong" creates more intake noise (which gives you the sensation of more performance), it does nothing for performance or at least no more than tribal graphics would give you.[/quote]hence why this is usually (and ideally) coupled w/ a change to a K&N-style intake filter; which [U]does[/U] allow more air flow
[quote]...No air flows through the bong and if no air flows through it, it can't possibly be a source of flow restriction...[/QUOTE]where is the inlet for the intake then? looked to me like the bong connected right up beneath the filter, where the air would come in, and for the bong to create a sound wave inverse to what is going past it, wouldn't the inlet on the bong need to have some air going past it? parked right up behind the front bumper doesn't seem like an optimal place for getting air PAST an opening.

Re: Aura Intake Resonator Bong Delete
 
I think he meant that air doesn't exactly flow into the bong, but that it's sucked in thru the intake by the engine

But then again, that doesn't make much sense either because with air being sucked in....that means air is flowing thru the intake

So maybe he should better clarify, LOL


Nice post though!!! (was finally able to see the pictures)

What the heck can stepping on the brake pedal do with the negative battery cable removed do? If there were any capacitors holding a voltage or flash memory with data stored, with the negative terminal open, there still wouldn't be any discharge as far as I can figure.
So how does this procedure do anything to the memory?

Does this go for cat-back exhaust enlargement and free-flowing exhaust swapping? I did it probably 4 months ago, so the fuel trim would of adjusted by now anyways, right?

it [U]definitely[/U] applies to those kinds of mods. You're flowing more air through the whole system, so you want the car to know the proper fuel. it has probably adjusted by now, but resetting your fuel trims (either by a programmer like the dashHawk or by disconnecting the battery) is a good idea whenever anything drastically changes with your atmosphere or the airflow to your engine. i do it between fall & winter, and winter & spring, and also if i travel to a drastically different altitude and plan on staying there for any longer than a couple of days.

Thanks. I went ahead and removed the resonator bong about 3 weeks ago, and have been tempted to add a post. So here it is.

It only took me 20 minutes to do. It was easy. It did nothing. I went ahead and disconnected the negitive terminal of the battery, and grounded it to the positive post for a half hour also. Also swapped the air cleaner to a K&N. Still makes no increased nothing. A waste of time. And now there is a easier way for water to get into my intake,... if I decide to drive through a levy breach.

Any way, I say don't waste your time SaturnFans, if you're thinking about it. I also say if you want what was touted at the begining of this post, then do what I have already done, and it is the favorite mod that I have done to my Aura. Remove the stock exhaust system from the Cat back and replace with a 2 1/2" pipe and add a Magnaflow resonator and Magnaflow muffller. You [B][I][U]WILL[/U][/I][/B] get the added H.P.(a few), you [B][I][U]WILL[/U][/I][/B] get the added racing sound effects, and you [B][I][U]WILL[/U][/I][/B] still wish you had a V8 when that Porche Turbo blows your doors off on the 405 at 1 in the morning. Whoops,....I sounded cool though!:cool:

maybe you didn't pay attention to where your the hole to your intake was before, and where it is now. it's actually about 2-3" HIGHER than it was before, so if you want to ***** about that angle, you should ***** harder about the stock setup.
[quote]Any way, I say don't waste your time SaturnFans, if you're thinking about it.

i must say i used to view you with respect on this board but that was clearly mis-placed.

btw, if you're panties are in that big of a bunch for it not doing anything and being "more prone" to hydrolock, put it back on in another 20 minutes.:rolleyes:

Yes, it was a thought process of mine. Also considering that the airbox and location looks similar if not identical.

Re: Aura Intake Resonator Bong Delete
 
Removing the intake resonator on a 3.5 is the exact same process as on a 3.6. From what I can tell it should be the same for the 2.4 as well. From what K&N's website is saying all three engines accept the same air filter (Part #33-2249). Someone correct me if they have more info on the 2.4 resonator.

I removed the resonator on my 3.5 and I'm happy with the results. Its cheap and makes a noticeable difference.....why not do it?

Re: Aura Intake Resonator Bong Delete
 
I just removed mine last night. Like stated before it's cheap, only costing a few minutes of your time, and you can tell a slight difference. A difference both in sound and slightly in performance. This will be good enough until I get the funds for this [URL="http://cgi.ebay.com/ebaymotors/05-06-PONTIAC-G6-3-5L-V6-COLD-AIR-INTAKE-FREE-K-N_W0QQcmdZViewItemQQcategoryZ38634QQihZ023QQitemZ360079352899QQrdZ1QQsspagenameZWDVW"]http://cgi.ebay.com/ebaymotors/05-06-PONTIAC-G6-3-5L-V6-COLD-AIR-INTAKE-FREE-K-N_W0QQcmdZViewItemQQcategoryZ38634QQihZ023QQitemZ360079352899QQrdZ1QQsspagenameZWDVW[/URL] Its for the G6, but sometimes you have to think outside the box.
