Description 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.
