I'm interested in upgrading my fuel injectors after reading about these Volkswagen AAZ 2-stage injectors. As I understand, they offer a slight increase in power and fuel economy and the engine runs quieter and idles smoother. It seems most people are putting them in the OM617 turbo engines, but I'm curious if they are compatible with the OM601. I also stumbled across a few threads that mentioned an "angled injection" upgrade for OM60x engines that is supposed to improve fuel economy, but haven't been able to find more detailed information, part numbers, etc.

Really? I'd never heard of that. Sounds interesting.

You need to jump over to S . T. D dot c o m. These are not the silver bullet you are thinking they are. They have 2 pop pressure settings in the AAZ (they pop "twice" per injection cycle vs. OEM just once). A former / banned member hyped these up a bunch and once he got them, he couldn't wait to sell. You will most likely not see any increased performance or mpg. If you want more fuel for the OM617, then you will need a different nozzle and a mod'd IP.

That's a shame, it sounded so promising. I've been planning to order a set of Bosio 314 nozzles from IDParts, but they are out of stock until early next year. Do you know anything about the inclined/angled injection for OM60x engines?

Things you need to check on.

The Angled Injection Injector thread into the top of the Prechamber so the Injectors are threaded with finer threads that are closer to the tip of the Injector.
The holes in the Prechamber are in a different location and that may mean the Piston Crown has shaped differently.
Angled Injection Prechambers use the Splined Prechamber Rings.

While I suppose all of the Parts could be found at a Junk Yard to do the change if the Pistons are not compatible that would kill the job.
I don't know if the Angle Injectors have the same threads at the top of the Injector for the Hard Lines.

You would need 2 types of Prechamber Ring Removers and the double ended Prechamber Puller that has both the fine and coarse threads on it and a Slide Hammer that fits the Prechamber Puller.

When swapping the prechambers you would need to find some way to insure the proper protrusion into the combustion chamber of the angle injection Prechambers.
