Has anyone developed any brether filters for the vq 3.0 because i see a lot of hondas with these and i would much rather have that then the stupid hose we have. anyone have this already or know of this??

 

What's a breather filter for?

 

The ones at Autozone/Advanced auto don't fit good, the inlet is too small.

i asked this question a while ago i think...at a meet , i saw someone with a small filter on the valve cover i think it was. front center of the engine block
aperently it doesnt do anything at all. someone said it was a breather valve for gasses and the hose goes to your intake and gets burned back through your engine..not sure what's true.
but i was thinking....if youre getting used air recirculated back around again from this valve...wouldnt there be some kind of gain from not tainting the clean unburnt air [optimal] in your intake passages? i would guess your mpg would go down but maybe youd get somehting out of more pure air?
i dont know anything!

...if you do it i will too

 

A breather filter relieves your engine of positive crankcase pressure and recycled carbon vapors from your engine, which cause loss of throttle response due to build-up on the throttle body. The Breather helps resolve that problem, by venting the vapors into the atmosphere.

I used the one from AZ but had to "bore" it our with a knife etc..

 

does it really affect warm up??

 

id think if you did get a breather filter like those on hondas, itd just be purely cosmetic. I mean, come on its a short hose that was on there at first for chrissake, how would a filter give any positive gains. They do look better than just a hose there though

 

who knows til you've tried....maybe a placebo effect like a tornado or a electricsupercharger...

 

No peformance gains you 's Just keeps the intake tract a little cleaner ...

 

do you still have it on? got a pic?

 

any possibility this keeps the TB clean since spent air isnt being re-circulatecd back in, thats a reward itself IMO

 

i just like the way it looks and if it does anything than thats just icing on the cake

 

well...wouldnt it help because the warm air coming from the valve cover is now cut off from the intake??i dunno just a thought i had...

 

This is part of the PCV system and is emissions related kinda like the EGR system. Read this for a more indepth explanation. Yes its for another car but the system is similar to ours. And yes, employing a breather filter will help the engine but might not be good for emissions.

I have seen some org members use this anyway but its been a long while since I've seen those threads. Without the search function, its pretty hard to locate them anymore. I wouldn't worry too much about this breather filter. If you want to try it anyway, go for it.

**Edit**

Just saw this also. Notice it says that its not for use on emission controlled vehicles.

 

well....what if you take it off before the smog test...sorry i didnt read the stuff yet...

 

If you've read the article, you will realize that u will need two breather filters. Read on and find out why.

 

yeah i wasnt planning on just using one...

 

There ya go , sorry for the size . .

 

is your hacked airbox upside down??u think it produces any gains??

 

where is the second one located, I only see the one in the picture ...

I also vote mostly cosmetic...

 

It sucking all that hot air in from the engine??? I highly doubt it, this produces a pretty loud intake growl though.

 

i tried the upside down method and noticed that it makes no difference in the sound..
