For sale is one Greddy type S BOV. I've had it on my car for approx 4,000 miles. I purchased the type RZ and I no longer need this BOV. the above picture is not my BOV, but mine is identical except for a little usage wear. Works fine, I just don't boost enough for the spring I guess and I surge at low RPM, so I switched BOV's before I have to switch compressors. These were retailing new for $250, I'm just looking to recoup some of the cost of the RZ. Here is a link to what the Type S sounds like: http://www.youtube.com/watch?v=-uNMqxYPs94 Again, not my BOV, but it sounds identical. 

*EDIT* now comes with the used bolts, gasket, hoses. *EDIT*
