Who Knows What This Is?

This was connected between my blow off valve and intake manifold in the middle of 2 vacuum hoses - it looks like its all melted etc and i think it was causing problems with the blow off valve coz it was only working sometimes...

anyway ive connected a vaccum hose up without this and everything seems fine now - so just wanna know if anyone knows what it is? and do i need to have it connected for any reason???

thanks.

i have no idea what it is!

but unlesss you have tapped a hose into this vaccum line there's no need for anything there..

leave it out and your car will be as a stock one..

hmmmz possibly an old one way valve? not to sure to be honest

I got one in the same spot, it got HKS on it , I got a HKS BC so i guess it got something to do with that

I Got a very similar thing with my New GReddy Profec and it tells me that its a filter. On my boost controller it Filters the Fuel Pressure to sence boost pressure for the Unit

I got sometihng like that on my SSQV, figured it was jsut a reducer since the "nipple" thing on one side is larger than the other.

this is a hks one too - it looks like its some sort of little filter but i cant see why u would need it... anyway i had it off all nite and drove a fair bit with no problems.. its all melted and f$cked anyway from being next to the heat shield. i wouldnt mind buying a new one if anyone knows where i can get it???

Its a filter. Commonly used on EBCs to prevent vapours from entering the unit and f*cking the map sensor up. The only reason I could see it being used on a BOV would be for the same purpose, keep vapours from going into the end and turning into liquid - possibly f**king the operation of it? Personally I dont think a BOV needs it, definately a plus for anything electronic thats getting a pressure signal though.. vapours are bad!

It is a one way valve. That is all. They could have incorporated soe type of filtering device into it but you should find that you can blow through it but not suck.

why would you have a 1 way valve on a bov hose? that would make it either stay permanently closed, or make it leak something shocking.

exactly, i doubt its a one way valve.... unless the BOV vaccum line was tapped into the brake vaccum line, and that came from the brake side, but i dont think thats what's happened here, if it is, put it back, quickly!

its a filter so no oil , dirt goes in.
