FAQ
How many do I need?Nozzles are sold individually. Order six to service all cylinders on a 5.9L Cummins.
Do I need tuning?Yes—calibration is strongly recommended to optimize EGT, smoke control, and drivability with ~46% over fuel.
Will this work with stock turbo?It can run on a healthy stock charger with conservative tuning, but an upgraded turbo is recommended to fully realize the +125 HP potential while controlling EGT.
Is this CARB legal?No. These performance nozzles are for closed-course competition only and are not legal for on-road use where emissions laws apply.
