low vs high imp, they are just different types, neither is going to be better. You can replace the low imp injector with high imp by just chaning the wiring and resistor pack.

A low impedence injector will react more quickly but will heat up much faster, thus heating the fuel as it goes thur.



A high impdednce injector runs cooler but will be slower reacting.

overall, which is better then?

they aren't better or worse just different
