I am curious if anyone is running Monark spray nozzles or complete Monark injectors in their car or using Fratelli Bosio spray nozzles.
If so please comment on the results.

I have never heard of Monark. Many users here have used the bozios with good results.

These 2 companies sell both Bosch and Monark spray nozzles and also complete Monark new injector assemblies.

I had never herd of Monark until I found the company on one of my continuing internet searches for parts. They are supposed to be used as a set. They are not considered higher performance nozzles as the Fratelli Bosio nozzles are but comments from the internet said that they were quieter at idle. The Monark main office is in Germany.

We have the Bosio's on both of our SD's and they perform VERY well. Great performance and mileage.

nozzles-OUTSTANDING. According to their catalog (print German) they updated the DN(O) design for MB OM61X and OM60X (IIRC four times since '79 or so) resulting in smother running and better mileage. BUT then again, the old Bosch set had 200K miles. I'd like to compare new to new but don't really want to go through the trouble...

That's true. A part number for many of us (OM60X SD 265) have three different catalog numbers for the same engine. Even though the DN(O) SD number could be the same, you still need to match the 9 digit catalog number. I haven't toured the factory yet (still waiting to see if I can) but Monark's quality control seems orders of magnitude away from stuff made in Asia.

Thanks for you comments.
They also cost several dollars less than the Bosch nozzles (which people say may be coming from India now) and are about $16 less than the Boiso Nozzles. I am presently running some brand X type nozzles made by 7 Diesel @ $11 that are made in Italy (I got them from US Diesel in Fort Worth Texas). They sure smoothed out my cars ragged idle.
I have a Nozzle Tester and I worked for 5 years in a diesel fuel injection shop so I rebuilt the injectors myself. The car has been running since Feb 07 with the 7 Diesel nozzles but after a years use I want to pull them test them and see how they held up. I was thinking to replace them with the Monark nozzles.

I have bosio nozzles in my 603. Seems to run fine. It's a little naily at idle sometimes but that may be normal. It's smooth as a top at idle on WVO/diesel 50/50. Acceleration is perfect and very fast.
