I have 3 sets of these available. They are all brand new in the package. $200 per set + shipping if needed. Located in Kentucky.
They fit all the 2.5L Turbo WRX models I believe. 2003-2013.
I used these sets of valves in a rally car several years back and they worked out great. These are just extra sets I have laying around. Seeing as I do not own the car or a WRX anymore they are doing me no good.
If you have any questions feel free to contact me. Once they are gone they are gone though, I am not a shop and do not have any more.
