2-Piece Injector Set for Kubota Excavator Engines — D722, D902, D782, Z482 & Z602

Mini excavators and compact construction equipment work in some of the harshest conditions imaginable — constant load cycling, dusty job sites, and long operating hours. When injectors degrade, you lose the crisp throttle response and fuel efficiency that keep your machine productive. This 2-piece set replaces both injectors simultaneously, restoring factory-spec combustion and keeping your Kubota-powered equipment on the job.

Built for Construction & Excavation Demands

• Kubota-Spec Fuel Atomization — Precision spray pattern matched to OEM specs for D722, D902, D782, Z482, and Z602 engines
• Complete 2-Cylinder Coverage — Both injectors replaced at once for balanced combustion and uniform power delivery across all cylinders
• Responsive Under Constant Load Cycling — Consistent fuel metering during the stop-start, high-load cycles typical of excavation and lifting work
• High-Pressure & Heat Rated — Engineered to withstand the sustained high-pressure cycling and thermal stress of heavy equipment operation
• 100% New — Not Remanufactured — Full service life from installation; no worn nozzles or compromised seals
• Direct OEM Replacement — Drop-in fit, no modifications or adapters required
