  • SUBARU FORESTER (2001-2005)
  • SUBARU IMPREZA (2001-2006)
  • SUBARU LIBERTY (2000-2006)
  • SUBARU LEGACY (2000-2006)
**They are a direct plug in replacement for all 2001-2005 and some 2006 Subaru Impreza WRX and STI, later STI and some Foster, Liberty, Legacy but may require tuning for best performance. They are an ideal upgrade if you want to achieve 300hp at the wheels or if you choose to run a larger turbo such as a VF30 or VF34 or increased boost.


The 565cc "pink" injectors are high-performance injectors for Subaru found on the high horsepower STI, STI-RA, and S202 Impreza models. These injectors are factory rated at 525cc but because of the common "under-rating" system of Japanese manufacturers, these injectors have been independently tested to flow 565cc. We recommend the use of these injectors for applications of 240whp-300whp. A very good compliment for all IHI VF-series turbos.
