07.5+ Cummins 6.7L Nozzle Set from S&S Diesel; ~SOLD AS A SET~ EDM/Honed SAC Nozzle; Various Sizing from Stock to 100% available. Nova Nozzles are NOT available for purchase as a stand alone item. It is ALWAYS recommended to have your injectors assembled and balanced by a fueling professional. If you would like to get a set bigger than 100% over, you will need to get your injectors sent in for S&S to install and calibrate. Give us a shout for an estimate on this cost. For 6.7 Injectors, the most they can flow with stock bodies is 200% over. Any more than that will require body mods.
