Subaru Rates these injectors at 525cc, other companies have rated them at 510cc, 520cc, 550cc, or 565cc, but when flow tested they consistently flow 565cc, so we have decided to go with the lowest number. STi pink injectors use the same clip as 02-05 EJ20 WRX factory injectors for true plug-and-play installation. Because these are a genuine JDM Subaru part, these will will have good response and smooth idle. These will also work with UTEC & Accessport maps designed for STi "pinks." These are high-impedance injectors, sold in a set of 4.
