This electronic unit injector (EUI) is a direct, OEM-equivalent replacement for Ca-terpillar 3406E, C15 and C16 diesel engines. Cross-referenced against OEM part numbers 102-2014, 102-6230, 102-6236, 103-4562 and remanufactured numbers 0R-4119, 0R-4118, 0R-4300, it is a true bolt-on fit with no core required.

Each unit is flow-matched and 100% bench-tested for injection pressure, spray pattern and delivery volume — delivering consistent firing, faster cold starts, better fuel economy and lower smoke across the full load range. The hard-coated plunger resists wear from today's low-sulfur diesel, extending service life between overhauls.

Ideal for Class 8 on-highway trucks, mining and construction equipment (including 385B/390D-class excavators), plus industrial and marine applications. Always verify fitment by engine serial number (ESN) before ordering.
