The big question would be. Why are you replacing your injectors?

How do you know your primaries are bad?

Send the injectors out to www.witchhunter.com if you believe they are bad. Only $19.00 per injector to clean and test and quick service.

If you are hell bent on getting new injectors then forget about all the BS and find a place that sells them according to your year make and model.

Peak and hold = low impedance

Saturated = high impedance
