hey im looking for a good quality breather filter. i just recieved a weapons r one that i purchased from this site and its to small and looks like a small plastic toy. so im going to send it back for a refund.
my question is for the 4th gens, where do you buy and what brand is best regarding a small breather filter. someone just direct me on the right path, with info, brands, and a link/website,
thanks
here is the link of the weapons r that wasnt the right size:

Honestly, those K&N style ones aren't that great. They don't get the really small dust/dirt pieces.
Proper breather filters have this white gauze like, foam like stuff in them. They work great, really keep the crankcase clean.
Go figure, the proper part works better than the performance/rice version.

Its a rice mod! Don't do it. Keep it stock. Well thats my 2 cents. But if you insist i would check your local Autozone or Pep Girls

Anyone know what a breather does?? Its a way of the engine to "clean" itself pretty much. By throwing carbon deposits back into the intake to be burned in the combustion process. The "breather" doesn't actually suck.
well i want to replace the silicon/rubber hose that goes from the crank case to the injen intake, thats all im doing. a small breather filter will do the job, will check at autozone see what they have.

I have heard mixed reviews on this, some people have done it and had problems I think, but the stillen suoercharger kit came with one to use. I will try to search and see who had problems.

krismax, a breather might yield 1-2 hp on a big block maybe. Do you even know why it's there and why we don't have one? And LudeAEM, read up, this is the actual reason.
Inside the crankcase, when the engine is running, blowby, and fumes from oil oxidation are produced. Also, when the engine gets warm, the gasses/air expand as well. If there were no outlet for the pressure, seals/gaskets will blow. Which is why a PCV needs to be cleaned/replaced when it gets clogged. Because if you don't, you'll start blowing out gaskets/seals.
Because the majority of the gasses leaving the crankcase are volatile hydrocarbons, to reduce these emissions, they are vented back into the intake stream, and burned again.
On the VQ in the 4th gen, the front bank is directly vented to the intake. This is the most common place to add a breather. And you know what? I recommend it, but with a proper filter, not thoe oil/gauze ones. Why? Because those fumes have deposits, varnishes, etc, that dirty up your intake track, I prefer not having it connected. The negative part is, you are releasing a few more hydrocarbons into the air (not anywhere near as bad as say even spilling a little gasoline). Just make sure you have a good filter there. Why? Because we all know how dusty/dirty our engines can get, and think about all that stuff flying around in your engine bay when you're driving around.
krismax, now that you know what a breather does, do you think that's actually going to make even a 1/10 of a horsepower difference? Allowing crankcase gasses to vent, or to draw the small quantity of fumes into your intake again?
Ceasars Chariot, any quality auto parts store should carry atleast one brand of good breathers. Just make sure the breather is the same diameter of the nipple coming off the valve cover, and get like 2" of heater hose with two band clamps to hold it all together. I'll be the first one to admit, not bling, but is definetly a better choice over leaving it as is and adding more varnishes and deposits to the throttle body and beyond, and definetly better than those oil gauze breathers that definetly let in many small dust/dirt particles.

Good info ,The reason i say a power increase is because my friend has a STI and on one of the wrx forums a guy dynoed 3 more hp with one hooked up . They said because of turbulence Originally Posted by Sin

Thank you. I knew taht was the reason... all I wanted to do is let poeple konw its really a pointless "modification". Like you said, its for clenseness and the enviorment.Originally Posted by Sin

If it's so pointless why did you waste your time arguing about it? Ceasar just go to autozone, they have them for a few bucks. The one I have was a bit weird cause the little rubber piece had a very small hole on the inside but the wall was thick. To use the stock hose you'll need to trim it a bit.
hey sin...so how many those "K&N breather" you think i should get? 1 for the one next to the valve cover and 1 for the pcv valve on the intake path?
also if i pick up 2 of those K&N breather, or intimidator...should i pre-oil it just like a regular intake cone filter?

Don't use the stock hose. With heater hose as cheap as it is, and an oe replacement hose many times more, it just don't make sense. Hell most shops will chop you 2" (all you need) for free.

You're joking right? Don't get those K&N oil/gauze filters. Get a proper breather filter. Just get one for the front bank.Originally Posted by happyricefob

Nothing to do with being a newbie. I explained it all in that long post, and then you just asked how many K&N breathers to get, and whether you should oil them.
It's all in that post man.

there's a hose that's going from the nipple coming off the valve cover to the intake. if you instal a breather filter, what do you with the hose(or the tube for the hose) to prevent unfiltered air intereing the intake?

hey nismo i hope you don't mind letting us borrow your picture as an example for the breather setup. anywayZ here's how it supppose to look like
i like that little 90 degree angle , my main beef is with the top hose going over the injen intake. i have cut that dang thing once to shorten it and its still in the way. just bothers me. so i got to checking out the breather hose thing.
thanks for the info on this, will drop by the autozone store and see what i can piece togeter.

1. the diameter of the cap for the PCV valve is 3/4 inches.
2. you will see plenty of K&N/APC breather in your local autoshop, but those won't fit directly to the front bank. the diameter of those K&N/APC breather are actually 1/2 inches.
3. noticed nismo's setup of the K&N breather. i believe he cut the stock hoses which used to lead from the front bank to the PCV valve, put the cap on the PCV valve, and insert the K&N breather to the cutted hoses. that's why his K&N breather sticks up, not side way.
4. i will need to PM him about how it is done.
5. local autoshop's K&n breather should be anywhere between $10-$12, just like 2kracing. if you want a K&N breather specifically with 3/4 diameter, which will fit directly into the front bank without cutting hoses, it'll cost around $25.
i'll keep you posted...
This is nismo's "L" breather setup:

To get the breather onto the "L" PCV adapter, I had to use a dremel and grind off some plastic off of the PCV adapter so that it was small enough that it would fit onto the breather, then I just clamped it on. I hope that helps you. They make different size breathers so if that doesnt work, you might have to buy one that has a bigger opening.
This is his "straight" setup:

i'm gonna try the L setup tomorrow. if i succeed then i'll post instruction and credit to nismo. and possibly summit to luke (gtr_rider) at vqpower.com.
