Remanufactured in USA/Canada/Europe OK.
Remanufactured by an ADS member, GREAT!!
My son who lives in the Netherlands got some European Remanufactured Common Rail injectors for his BMW and they are doing well.
If they are rebuilt in China, sorry, not for me.
I would check out
http://www.diesel.org/ for ADS members who are reputable repair/rebuilders/remanufacturers for Diesel Injection Components and Turbochargers.
When I was in the repair shop business and ever since then, I have used ADS member shops for any diesel injection pump, injector work or parts. They stand behind their work and I have not been let down.
