FAQ
Is this nozzle sold individually or as a set?Sold individually. Order six nozzles to service all cylinders on a 5.9L Cummins.
Do I need an upgraded CP3 with R3 nozzles?Yes—an upgraded CP3 (e.g., Dragon Fire 10mm or larger) is recommended to properly supply fuel at R3 flow.
Will these fit late-2004.5–2007 trucks?No. These R3 nozzles are for early 2003–2004 5.9L common-rail applications only.
Are these legal for street use?No. They are intended for competition/closed-course vehicles only.
Legal/Emissions
All Industrial Injection Performance Products are not legal for “on-road,” “off-road,” or “dual-use.” Competition/closed-course only. Compliance with all federal and state emissions laws is the customer’s responsibility.
