I got some injectors with and intake manifold on a trade deal. I was told that the injectors were 24#, but they guy never used him and he got them from some on else. I know from experience that 24# injectors have a blue top & I checked the injector identification picture most of us have. These injectors have a grey top and the part # on them are E67E-B4B. I did a little search on the internet and I found that they maybe 14# off a mazda. Please help. Oh on the other side of the injectors it has 9F593.
