i have an 04 sti, it has APS parallel fuel rails and i have never been quite sure since recently owning it what injectors it had, having it look it has turquoise colour inejectors with the number 0280155777 written on them, they appear to be bosch injectors?

now i cant make sense on the net it says 200cc? it also says "which flows 150 GPM @ 3.5 BAR. Resistance 12"

what does this mean? obviously the standard pink injectors are 550cc arent they? these cant be less can they? is it to do with spray pattern?

 

Someone may have altered the injectors, for example I have some "blue" WRX injectors which have been altered and flowed to 650cc by milleniumracer on here. Does the car run OK??

thanks shaun, yes car runs fine! was just curious, quite new to the subaru scene so all a learning curve!

 

Mine were pink, my modified blue injectors are rated at around 800 cc

The normal STI injectors are as you said pink and 550cc there are also some blue ones which i think are 560cc and came in the likes of the spec D.
