2-Piece Injector Set for Kubota D902, D722, Z482 & Z602 Engines — Compact Size, Uncompromising Precision

Kubota's small-displacement diesel engines are workhorses — powering compact tractors, mini excavators, generators, and utility equipment through thousands of hours of hard use. When injectors wear, the symptoms are hard to miss: rough idle, increased fuel consumption, hard starting, and loss of the smooth, reliable power these engines are known for. This 2-piece set restores factory-spec fuel delivery and gets your equipment back to peak efficiency.

Pro tip: Kubota's D-series and Z-series engines are known for longevity — but injector wear is one of the few maintenance items that can quietly rob performance over time. Replacing both at once ensures uniform spray characteristics across all cylinders and prevents the second injector from failing shortly after.
