Cummins 5579415 XPI Common Rail Fuel Injector 2894920 for Cummins ISX15 / QSX15

1. Overview

The Cummins 5579415 is an XPI common rail fuel injector for the Cummins ISX15 / QSX15 (EPA10-era XPI applications). Three sources pair it with the previous number 2894920: a remanufactured-injector specialist listing, the Shumatt technical file for the 2894920 XPI injector, and a remanufactured-forms listing. ⚠️ One official-brand flyer (Interstate-McBee) prints the same kit pairing with the old number as 2892920 — one digit different from 2894920. This page uses 2894920 as the main paired number and flags the 2892920 printing as to be confirmed; always order by the engraving on your old injector. Remanufactured forms include 5579415PX (NX / RX forms are also listed). Note: XPI injectors are Cummins-made — there is no Bosch equivalent number for this injector. 100% brand new, bench-tested before dispatch and built to OE specification.
