Air Intake Cleaner/Silencer?

this thing is attached by a screw/bolt to the air filter housing ... the air intake hose goes from the air filter, to this thing, then to the engine ...

does anyone know if this part is a silencer? on usedpartslive.com [where the image is from], it says its an Air Cleaner Assembly, but i know on my subaru there is a part like this that serves to silence the air intake lines

do i really need this part? can i just cap off the air intake hose in the middle so that it only goes from the air filter to the engine?

if you need me to take some more pics of the pieces i took out or what im talking about, lemme know

so basically if i wanted to make my intake more like an SRI, i could cap that part off?

because right now its on the floor of my garage along with the rest of the intake pieces, so theres no need to put it on unless i have to ... but i have to find some way to cap that hole off in the intake hose

right now i have 4 coffee filters over it, lol ... im just putting them on to see if the sound of the intake is any different :p

When in doubt, Tear it out.

lol I doubt you need it. toss it.

for those who dont know, this is how the pieces line up ... except theyre in the engine bay instead of on the floor

what i have done temporarily is this:

i might stop by home depot to see what i can put in its place that is flexible but wont let air pass thru ...

oh, and for those of you with the 5S-FE that have cut out the bottom half of the air filter box, how did you do it ...
i cant see a way to allow more air in from a cold location without losing the air filter too...

maybe put a cone filter in place of the silencer? although i think that might decrease performance, because then you have 2 inlets that are perpendicular ...

maybe one of the moderators or engineers of TN will post their thoughts?

The Gen5 and Gen6 are different, but mine had two intake silencers/resonators. All I did was use some black duct tape and cover up the holes. I've noticed that when accelerating, it sounds alot beefier then before. It's one of those great free mods.

if u want to can take it all off, the performance gains or loss are probalby no more the 1hp either way. the only things u need to be concerned about when modding ur intake are: 1. are all sensors and needed hoses attached. 2. is there a water bypas(if the intake is sitting low enough). 3. is this going to impeede on any other enigne functions.

i need to get some good tape or a plastic cover - im afraid it will rip those coffee filters and suck it into the engine, that would be bad

if you want to go with ghetto rig, you can probably put two layers of mosquito netting before the coffee filters. That way, even if the coffee filter rips, you still have the netting to prevent it from being sucked in.

for now im gonna get a 2 1/4" inlet cone/cylinder filter from autozone if they have one ... just until i can find a cap

i dont trust coffee filters :lol:

yeah, we only have 1 sensor ... makes it easy to install a SRI/CAI

i was thinking about removing the stock box, putting cone filter on the stock intake hose, and i could put the sensor in this extra opening i have now ... but we'll see what i come up with when i get a chance to goto some stores

You can cap it off & it will be louder, but you'll probably loose a horsepower or three in the process.
If you're going to go a short ram do it right. Attach the sensor to the throttlebody, and the filter to the sensor. The shorter, the cripser the throttle responce will be.

^ he means find a way to mount your map sensor really close to the throttle body and then just attach the filter to that adaptor

I'm under the impression that your map sensor is just a probe? I've never dealt with the 5sfe intake....


And I would use some duct tape to cover up the bottom resonator/silencer hose. just make sure that you wrap it real tight afterwards as well so it can't get sucked in. If you can find a hard plastic cap of some sort (that won't vibrate as vacuum is applied) that would be even better. I doubt that you'll lose power from removing it though. The turbulence created won't hardly effect the air
 
#17 ·
yeah, just a small probe ... you can see it laying in the bottom half of the air filter box in the picture of the engine bay

i was worried about turbulence, but i didnt know how much it would cause because its only a small ditch in a tubing thats almost 3" wide i believe

ill put some tape over it tonight [i drove the subie today so i wouldnt have to actually use the coffee filters] ... and then ill go searching
 
#18 ·
ok, its taped up ... duct tape doesnt adhere well, but with the clip on there its pretty much as tight as possible

it still vibrates a little bit, but not much

ill see what happens tonight when i go out - hopefully my car wont explode from sucking in duct tape :lol:
 
#19 ·
It's not the turbulance. It provides an additional amount of volume of air to the engine to help cope with different engine demands.
You may or may not loose anything, but the majority of the time - when you kill off an OEM intake resonator, you're going to loose power. they're there for more than just sound suppression typically.

well, i can deal with losing 2-3 hp .... as long as i dont lose 2-3mpg with it

im used to a weak engine [good ol' 5S-FE], but i love the gas mileage i get...

^yeah that's why I only tweaked my A/F ratio and throttle kick-down cable... back in the day before i even had my license and my mom still drove the camry.. LoL good times. :)
