Hello, let my start off by saying I'm new here, I just bought my first WRX last weekend. The previous owner installed some things I don't really agree with which I am changing out for either stock or better replacements, one of these things is an HKS blowoff valve. From what I am reading here it sounds like I should go back to the stock bypass valve, the problem is I have been looking everywhere online for a week straight and I cannot find a single one, new or used anywhere. I don't want to go to the stealership because I know it will end up costing me more than if i just get a new aftermarket recirculating one, and since I'm a college student I'm kind of on a budget. Does anyone happen to know where I can find one? Believe me I have spent a good deal of time searching, I'm not new to forums so I know better than to ask before I have looked for myself.
