S&S Diesel Motorsport nozzle sets for the 2007.5–2018 6.7 Cummins, sold as a complete set. Built with EDM/honed SAC nozzles and available in sizing from stock through 100% over. These are nozzles only — not fully assembled injectors. Professional assembly and balancing by a fueling professional is always recommended after installation.

Nova Nozzles are not available for purchase as a standalone item. Nova Nozzles are only available as part of a complete S&S injector set.

Sizing notes: For nozzle sets up to 100% over, order directly here. For sizing beyond 100% over, your injectors must be sent in to S&S for installation and calibration — contact us at info@hardwayperformance.com for an estimate on that service. The maximum flow achievable with stock 6.7 injector bodies is 200% over. Anything beyond 200% requires injector body modifications.

Important: Once this item has shipped it is considered final sale and is not eligible for return or refund in accordance with the manufacturer's policy. Please confirm your sizing selection carefully before ordering. If you need a sizing recommendation contact us before purchasing.
