The best injector nozzles for a W115?
 

Are these Monark injectors the best available option available for my W115 240d equipped OM616 motor or does a better option exist?

I replaced mine with Monarks and achieved very good results. I have heard they are as good or better than OEM, but it's hard to say for sure. Make sure you have a pop test kit and extra shims to re-balance them, and also a fine piece of sandpaper to lap the adjacent sides. Recommend extra caution to prevent specks of grime or dirt from getting inside. Balancing them and doing the job right seems more important than Monark vs. OEM.

If you have worn nozzles then any thing new will be fine

I'd have them tested and adjusted in needed by a diesel shop first.
