Hey all, I'm considering using a set of GM OEM LS3 injectors with the FIC (Fuel Injector Connection) extenders for my heads/ cam build.

FIC also recommended the new Siemens 42lb injectors.

What about the new Bosch Gen III skinny 42lb injectors, that already come with an EV1 plug and need no adapters at all?

The big two I hear of folks using are the ls3 and the white Bosch that came in the supercharged pontiacs. I have ls3 in my cars and it seem like it really likes them compared to racetronix.

Any other opinions?

I'm wondering now about the GTP injector spray pattern, is it correct for an LSx application?

Is the GTP spray pattern the same as the a 42lb Bosch Gen III injector?
