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.
