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 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

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!

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!

    • But there's the archetype for the name plate! Here's my view on that stupid TÜV ruleset. Buy a brand name aftermarket piece of equipment. In this case, the Mines front pipe we're talking about. Get it TÜV certified on the car. Damage the underside of it, say on a speed bump. Cut out the damaged section, replace with fresh metal. (For the sake of the argument only), continue doing that to the whole pipe until it is all gone, replaced with new metal. Is this grandfather's axe still the same front pipe? The design hasn't changed (much). The pipe walls are in the same places. The flanges are in the same places. It is functionally identical. How does this differ from a pipe that is ever so slightly different in fabrication (ie the number of welds in it, a few mm here and there in terms of where the pipes run, are joined, etc)? Anyone with 0.5% of a brain can see that there is absolutely no way that the performance (power, environmental aspects, noise, etc etc) of it can be any different than the genuine Mines pipe. Maybe even Mines made 2 versions of this design, with the same differences. How would anyone (say a TÜV inspector) ever be able to differentiate between them? And yet, they are so bloody anally retentive about this stuff. Mad. How upset would they be if you had the wrong spring washers on the flanges?

    • After a fairly extensive search using Japanese terms and checking Minkara etc, I couldn't find anything even close to your front pipe in the photos. I'm no expert but the two pipes merge really close to the flange connected to the catalytic converter which is rather unique from what I've seen, which makes me think it's more than likely a custom front pipe. The welds and 'more pipe sections than usual for a brand name pipe' makes it seem like a custom one.  Here's some photos of an old Mine's front pipe. You can see that it's just 4 pipe sections as opposed to 6, and arguably looks more like a 'production' front pipe:
