Review on Denso High Impedance Female Fuel Injector Connector Plug Pigtail - 6 Pack by Ryan Koser

After rebuilding the heads I had a rough idle and some hesitation when starting the 92 4Runner. I had the injectors checked and all passed and the Toyota technician told me to replace the plugs. I thought they looked really good four or five times. I had to turn them off so I replaced them with them and all the problems were gone. I wouldn't recommend taking it apart like another reviewer and then giving a bad review for not being able to use the factory pins in it. LOL don't reuse old parts or you're wasting time and money. Don't forget to solder the wires and wrap them with shrink tubing. Highly recommended
