So what's the difference between Low and High Impedence?

If you are looking for aftermarket injectors then what should you be looking at?

you should be able to get both as aftermarket.

off the top of my tiny little brain...

the higher impedance injectors have higher resistance. therefore they use a higher voltage to trigger them.

the lower impedance injectors have a low resistance and therefore need a lower voltage to trigger them.

s13 ca18det's use low impedance injectors, and therefore have a dropping resistor built into the system to lower the injector trigger voltage. its that big silver shiny thing thats attached to your stock airbox, and has quite a few wires sticking out of it!
