The CAT Injector 387-9432 (also referenced as 20R-8065 in reman form) is a HEUI injector designed for C9 engines operating in excavators, generators, loaders, and other heavy equipment. The unit delivers precise fuel quantities under high hydraulic pressure, ensuring improved combustion and responsiveness. This injector is ideal for engines showing fuel knock, black exhaust, low fuel efficiency, or rough idle. For fleet operators and repair workshops, replacing injectors in sets helps maintain performance consistency across cylinders. Because HEUI injectors depend heavily on high-quality engine oil for actuation, it is essential to maintain clean oil and ensure the HEUI pump and oil rail are functioning properly.
