Are these Secondary air filters? , do they make a differnce?, is there better air flow when installed.?

and can any one tell me where i can find them or what would i search for if i were to look on ebay.


Thanks.

 

From what I've heard these are called "breather" filters.

I've seen a lot of people put them on their valve cover when the intake doesnt come with a spot to connect the hose between the two.

In the second picture I guess they just rather have two breathers (the one on the intake serving no purpose) instead of using a rubber hose to connect the intake to the valve cover.

 

Also, you can get these on ebay and like Autozone and shit.

 

they have them at autozone,... i was told they add like 10 horse or so. lets see the dyno sheets after words and let us know how they work.

 

Whoever told yout that is mistaken

 

LOL hahahah 10 horse power that's pure bull shit , theres no way , but i'm pretty sure it's really good for the engine, more air

Alright thanks alot guys , i'll go check it out.

 

Come on man, people are such retards...
They are BREATHER filters for the PCV system. They do not add any horsepower... How would they add Horsepower? Impossible

They are NOT to be used on the intake pipe... Some dude I know (complete idiot, one of those dudes who gets LED windshield squirters, lol) put one onn his intake pipe, cause he thought it was cool... His car actually lost power, because the intake was trying to suck air through the small BREATHER filter...
You could hear it, like a whisting/whining sound (and NO, it didn't sound cool, so don't do it)...

Save your money, please

 

Breathers are completely unnecessary on a N/A motor. Use the hose like it is intended to be used.

 

yeah waste of time plus doest the tube that attaches the intake to the valve cover serve a puprose? i thought the sucking of the intake helped relieve some unneeded pressure actualy making the car work better then if you just had both of hte wholes plugged or with air filters

 

There Breather Filters and they used to be $7.99 at Autozone. I noticed that I lost power when I put them on rather than gain power, so instead I put a larger diameter hose running from my Injen Intake Pipe to this other chrome solid breather valve that is sealed but has a foam filter inside of it that way I don't suck up as much oil through my intake pipe. Seriously if you want the K&N mini breather valves then I hope your going for looks because they don't add any power because your sucking in hot air right next to the head and intake manifold and not allowing your intake system to get the cooler air down further away from the hot parts of your engine, and by keeping the hose connected your cycling out the hot engine air enough to where it will keep your engine a little cooler and you are getting plenty of sealed cold air from your 100 dollar intake system that you bought, that is why you bought it right? Lol take my advice I have removed all the EGR valves and tampered with everything there is with the intake manifold and vacuum assembly and don't waste your money or if you do then invest in what I explained above.
$8.00 for the sealed foam filled oil catching breather
$FREE just because I have so much hosing lieng around to connect from intake to PCV breather valve
and if your intake has other vacuum nipples on it then I would cap them unless you are usinig one of them for your Idle Air vacuum hose like me.
Hope this helps later luders!
