152-3680 Cat-erpillar 3406E/C15/C16 Fuel Injector (EUI) – Replaces 0R-9258 10R-2780

This electronic unit injector (EUI) is a direct, OEM-equivalent replacement for Cat-erpillar 3406E, C15 and C16 diesel engines. Cross-referenced against OEM part numbers 118-9035, 140-8951, 140-8993, 152-3680, 159-2497, 159-2631, remanufactured numbers 0R-4668, 0R-4893, 0R-9257 and new service number 10R-2780, 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, plus industrial and marine applications. Always verify fitment by engine serial number (ESN) before ordering.
