This set of 4 x 600cc fuel injectors are a drop in replacement for the EJ20 engines found in the GDB and GBA Subaru WRX. Will not fit the GC8 which uses a side feed injector.
We reccommend that customers check with a professional tuner for proper injector sizing and other requirements for your vehicle application.
