high, which is why you use the resistor box/ individual resistors

High is good for me, I have a Ford Focus, hahaha. So when picking injectors, does it have to have the exact same impedance or does it just have to be in the ballpark?

Also, what plug do they use? It wouldn't happen to be a Bosh EV1 would it? /wishful thinking

They are LOW IMPEDANCE which is why you have to run the resistor box. It adds resistance to keep the power drain low and not burn up the injector drivers.

You just have to keep it in the same ballpark, at least for a Honda ECU. I dunno about ford, chances are the stock injectors draw too much power for it's ecu :P

So will these injectors fit in my Focus? What do you guys do to get them to fit in your Hondas. I mean obviously DSM injectors can't be the same plug type as Honda's, or are they?

And on obd-0 cars they're plug and play, with the resistor box already installed.
