So whats up with this, there are 2 purple and 2 green injectors, both have different part #'s written on them. Does anyone know what the difference is? I swapped mine to WRX 440cc injectors anyway but I am just curious.
The injectors flow exactly the same amount of fuel; it's the direction of their spray patterns that are different. Since the intake manifold's runners are not straight on into the head's ports, each injector's spray pattern is directed towards the port. Hope that makes sense.
