I know for sure the Bosch replacement Nozzles for the 617.952s are from India but no one has clarified that is so on the 606 Engines.
We are not supposed to mention the competition with Pelican so I cannot mention the Name of the Comapny but a search for Monark Injector Nozzles ought to take you to the site.

They are made in Germany, they work fine and the are cheaper then the Bosios.

Since greazzer is rebuilding the Injectors he could be a good source of info on them.

Another issue is there is a lot of counterfeit Bosch Injector Nozzles out there and most of the reported ones seem to come from eBay.
