original 328-2584 Aftermarket Diesel Common Rail Fuel Injector Assembly 268-1835 387-9441 20R-8058 for C7 Engine 324D new injector original new original new injector

Engineered specifically for the C7 diesel engine family, this fuel injector is built around the 328-2584 OE reference and is fully compatible with the C7, C7 ACERT, truck variant, and industrial C7 engine configurations. The wide cross-reference coverage, including 3282584, 10R-4762, 10R4762, 20R-8058, 20R8058, 238-9808, 241-3239, 243-4503, 295-1409, and 387-9429, allows direct replacement on C7-powered trucks, excavators, loaders, compactors, generator sets, and agricultural diesel equipment without modification. Precision nozzle machining and tight assembly tolerances ensure stable injection pressure, accurate fuel delivery, and clean diesel atomization across medium-duty and heavy-duty operating cycles.

The injector operates through the C7 common rail fuel system, where the ECM controls injection timing and fuel volume based on real-time engine data. Pressurized diesel is delivered from the rail into the injector body, atomized through precision nozzle holes into the combustion chamber, and the nozzle valve closes firmly to eliminate post-injection leakage, dripping, over-fueling, and excess smoke. This working cycle preserves combustion efficiency, reduces exhaust temperature spikes, and supports the long service intervals expected from C7 engines used in construction, industrial, mining, quarry, and fleet service applications.

Available as new, original, remanufactured, rebuilt, or aftermarket replacement, every injector is supplied with protective packaging, clear cross-reference labeling, and pre-shipment testing where available. To maximize service life on the C7 platform, operators should use clean diesel, replace fuel filters on schedule, drain the water separator regularly, keep fuel lines free of contamination, and inspect for external leaks and electrical connector integrity. Final fitment must be confirmed by engine serial number, engine arrangement number, machine model, and original equipment configuration before installation.
