RC 550 injectors

[idt512]

I am buying a set of these injectors and was wondering how to tell if they are indeed RC 550s? Ive never pulled my stock injectors out to see how they look so i dont really know how to differentiate between the 2.

have RC engineering 550's.

VERY easy to tell if they are indeed RC's.

Mine say RC in red letters right on the injector. Cant miss it.
