If you are looking to put some power into your WRX/STI and get a steal at the same time, send me message and/or make an offer. I bought this kit online directly from either COBB or Submits. Its been a few years so I don't remember exactly, but it is in COBB box as shown the pictures. I never installed the injectors or even took them out of plastic, so they are brand new.
