As the title states, I found a blow-off/bypass valve in my storage closet that was for one of my old FC's and I can't find any information about this brand. I remember that I bought it from Japan though, so it's a JDM brand.
I attached a pic.

Anyone recognize it?

 

Pro Sperice... if you havent gotten that far yet Apprently no longer in production.

 

Yea, I got that far as well lol. I couldn't find any information on the brand though. Thanks for the reply. At least now I know its out of production.
Now here comes the big question: Does anyone want to buy it?
